CosmosSigner class

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

The CosmosSigner 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 secp256k1 elliptic curve.

Constructors
