FIELD OF THE INVENTION The present disclosure relates to compositions and methods for enhancing the stability and survival of microorganisms in inoculant compositions. BACKGROUND OF THE INVENTION Inoculant compositions comprising agriculturally beneficial microorganisms are well known in the art. See, e.g., U.S Patent Nos. 5,484,464; 5,586,411; 5,695,541; 5,804,208; 5,916,029; 6,569,425; 6,808,917; 6,824,772; 7,429,477; 8,148,138; 8,278,247; 8,445,256; 8,883,679; 8,921,089; 8,999,698; 9,017,442; 9,101,088; 9,234,251; 9,340,464. Because the effectiveness of such inoculant compositions generally depends on the ability of the microorganisms therein to survive and propagate following application, much effort has been made to increase the stability of agriculturally beneficial microorganisms in inoculant compositions. See, e.g., U.S. Patent Nos. 8,011,132 (describing a method of adding trehalose, sucrose or glycerol to the substantially stationary phase of fermentation) and 9,090,884 (describing the microencapsulation of microorgnaisms in a water-soluble encapsulating material). Nevertheless, there remains a need for improved compositions and methods for enhancing the stability and survival of microorganisms in inoculant compositions. SUMMARY OF THE CLAIMED INVENTION The present disclosure provides compositions and methods for enhancing the survival and/or stability of microorganisms in inoculant compositions. A first aspect of the present disclosure is an inoculant composition comprising one or more maltodextrins, one or more disaccharides and one or more microorganisms. In some embodiments, the inoculant composition further comprises one or more monosaccharides, one or more oligosaccharides, one or more pesticides, one or more lipo- chitooligosaccharides, one or more chitooligosaccharides, one or more chitinous compounds, one or more flavonoids, one or more oxidation control components, one or more surfactants and/or one or more drying agents. A second aspect of the present disclosure is a kit comprising an inoculant composition of the present disclosure and a container housing the inoculant composition. A third aspect of the present disclosure is a coated plant propagation material comprising a plant propagation material and a coating that covers at least a portion of an outer surface of the plant propagation material, said coating comprising an inoculant composition of the present disclosure. A fourth aspect of the present disclosure is a kit comprising a coated plant propagation material of the present disclosure and a container housing the coated plant propagation material. A fifth aspect of the present disclosure is a plant germinated from a coated plant propagation material of the present disclosure. A sixth aspect of the present disclosure is a plant part harvested from a plant that was germinated from a coated plant propagation material of the present disclosure. A seventh aspect of the present disclosure is a processed product derived from a plant that was germinated from a coated plant propagation material of the present disclosure. An eighth aspect of the present disclosure is a crop comprising a plurality of plants germinated from coated plant propagation materials of the present disclosure. A ninth aspect of the present disclosure is a method that comprises applying an inoculant composition of the present disclosure to a plant propagation material. A tenth aspect of the present disclosure is a method that comprises, consists essentially of or consisting of planting a coated plant propagation material of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS Figures 1-3 are graphs showing the survivability of desiccated Bradyrhizobium japonicum NRRL B-50626 on soybean seeds stored at room temperature and less than 20%, 35-40% or 70-75% relative humidity, respectively. Diamonds = soybeans coated with 300 µΐ Bradyrhizobium japonicum NRRL B-50626 suspension. Triangles = soybeans coated with 300 µΐ Bradyrhizobium japonicum NRRL B-50626 suspension; 300 µΐ deionized water containing maltose monohydrate (30% w/w). Squares = soybeans coated with 300 µΐ Bradyrhizobium japonicum NRRL B-50626 suspension containing maltose monohydrate (30% w/w); 300 µΐ deionized water containing maltose monohydrate (30% w/w). Figures 4-6 are graphs showing the survivability of desiccated Bradyrhizobium japonicum SEMIA 5079 on soybean seeds stored at 30°C and 11%, 32% or 54% relative humidity, respectively. Open circles = seeds coated with 300 µΐ Bradyrhizobium japonicum SEMIA 5079 suspension. Solid squares = seeds coated with 300 µΐ Bradyrhizobium japonicum SEMIA 5079 suspension containing maltose monohydrate (30% w/w); 400 µΐ deionized water containing maltose monohydrate (50% w/w). Open triangles = seeds coated with seeds coated with 300 µΐ Bradyrhizobium japonicum SEMIA 5079 suspension containing maltose monohydrate (30% w/w); 400 µΐ deionized water containing maltose monohydrate (30% w/w). Solid circles = seeds coated with seeds coated with 400 µΐ Bradyrhizobium japonicum SEMIA 5079 suspension containing maltose monohydrate (30% w/w); 300 µΐ deionized water containing maltose monohydrate (30% w/w). Striped squares = seeds coated with 200 µΐ deionized water containing maltose monohydrate (30% w/w); 300 µΐ Bradyrhizobiumjaponicum SEMIA 5079 suspension containing maltose monohydrate (30% w/w); 200 µΐ deionized water containing maltose monohydrate (30% w/w).
