Murmur Hash

This Mod allows the convertion of strings to murmur hashes as they are used by the game,
and the convertion from a hash to an inverted hash that when hashed again results in the same hash for further use in other mods.

This functionality has been part of the VT2 Bundle Unpacker[gitlab.com] for some time but was not accessible in the game itself.

The inverse hash is not the original string that was used to create a hash. Instead, it is a string of fixed length that, when hashed with Murmur, creates a hash identical to <input>.
While the primary version of the hash function operates on and creates 64-bit hashes, the engine sometimes uses 32-bit hashes. However, while a separate algorithm does exist, the game instead simply creates a 64-bit hash and cuts off the second half.

Create a hash value from a string:
/murmur_hash <string_to_hash>

Create an inversed hash value from a hash:
/murmur_inverse <hash_hi> <hash_lo>

The has value has to be split in its hi and lo part eg
0C5CF5FB0717AFCB --> hash_hi = 0x0C5CF5FB, hash_lo = 0x0717AFCB

Huge thanks to Minding who helped me make 64bit calculations finally a reality in lua
And many thanks to all the people that helped me with tools or general support while researching and testing the topic;
