Fix Long Number Crash

When entering very large numbers in a numeric entry box, the game can crash with an integer divide-by-zero exception. This is caused by a bug in Unreal Engine regarding grouping when formatting decimal numbers, and I submitted a PR (https://github.com/EpicGames/UnrealEngine/pull/11663) to fix it. However, Coffee Stain Studios would still need to incorporate this fix into their custom Unreal Engine and ship it in a game update. In the meantime, this mod allows fixing the bug, using a hook to replace the affected code with a fixed copy.

This mod can also be used in the editor. However, building the source code requires manually reconstructing part of it. We have to duplicate about 500 lines of code because we cannot hook the affected function directly (it is static), but the UE license does not allow publishing long fragments of engine code. The comment in Source/FixLongNumberCrash/Private/FixLongNumberCrash.cpp contains instructions on how to manually reconstruct the mod's code.

Note: This fix is already included in the editor builds since UE 5.3.2-css-68 (https://github.com/satisfactorymodding/UnrealEngine/commit/17c57b42b34b27e9e05ce93ba7c074b59aa38798), so you do not need to use this mod in the editor anymore.
