CosmosNist256p1Signer class

Cosmos nist256p1 Signer class for cryptographic operations, including signing and verification.

The CosmosNist256p1Signer class facilitates the creation of Cosmos signatures and provides methods for signing messages, personal messages, and converting to verification keys. It uses the ECDSA (Elliptic Curve Digital Signature Algorithm) for cryptographic operations on the secp256R1 elliptic curve.
