EIP-2333 about blst

[mratsim]

The keygen is compliant with H2C keygen spec not EIP2333.

You need to build your own EIP2333 key generator.

You can find my implementation here: https://github.com/status-im/nim-blscurve/blob/fd4956f/blscurve/eth2_keygen/eth2_keygen.nim

You will need to recreate HKDF mod r as BLST does not expose it it's internal https://github.com/status-im/nim-blscurve/blob/fd4956f/blscurve/eth2_keygen/hkdf_mod_r_blst.nim#L83-L127

If there is wider interest/demand, it can be added... There is a caveat though. One of the project's goal is to validate the implementation, and the scope is mostly fixed by now. Or in other words, such add-ons won't be validated.

Looking forward to seeing the EIP2333 implementation added in.

We could really use EIP2333 support as well.

Added blst_derive_master_eip2333 and blst_derive_child_eip2333.
