Add BLS12-381 curve:
...
- don't create "Mod" in curve parser: compile-time type incompatibility
- don't use "Mod" in const sections: compile-time type incompat --> create a macro to get montgomery magics instead of a const array

...
- no more monty magic "negInvModWord"
- no public "matchingBigInt"

Use Montgomery representation by default for Finite Field
...
- Fix montyMagic, modular inversion mode 2^2k was missing an iteration
- Fix test for buffer size in BigInt serialization
- Add UINT/Hex serialization for finite fields
- Montgomery conversion and redc
