CosmosETHSecp256k1Signer class
Ethereum Signer class for cryptographic operations, including signing and verification.
The CosmosETHSecp256k1Signer class facilitates the creation of Ethereum 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.
