Implementation of bls signature verification for ethereum 2.0

import { IBls, PublicKeyArg, SignatureArg, SignatureSet } from "./types.js";
/**
 * NOTE:
 *
 * This conditional block below is present in most functions and is Herumi specific to prevent
 * downstream issues in the WASM code. It is not necessary to validateBytes for blst-native
 * code. The check for blst-native is implemented in the native layer.  All other byte checks
 * for the herumi code paths are found in the herumi classes for performance reasons as they
 * are byte-wise, only are required for the WASM and will unnecessarily slow down the
 * blst-native side.
