Module secp256k1 

ecrecover precompile.

Depending on enabled features, it will use different implementations of ecrecover.

• k256 - uses maintained pure rust lib k256, it is perfect use for no_std environments.
• secp256k1 - uses bitcoin_secp256k1 lib, it is a C implementation of secp256k1 used in bitcoin core. It is faster than k256 and enabled by default and in std environment. Order of preference is secp256k1 -> k256. Where if no features are enabled, it will use k256.
