Takes raw structures from a decompiled 'Assembly - CSharp.dll' from a main.unity3d fusionfall beta client,
and transpiles them to gopenfusion's custom packet structure & tags. This requires a compiler installed,
since struct field padding is grabbed via the `offsetof()` C macro. Some manual rearranging of structures
from the disassembled source might be needed. This script can also be used to generate c-style structures
from the disassembled source might be needed. This script can also be modified to generate c-style structures
