    message: string | Buffer<ArrayBufferLike>,
    signatureBase64: string,
    useStrictVerification?: boolean,
): boolean

  Address of the signing address
- message: string | Buffer<ArrayBufferLike>
  message_challenge signed by the address
- signatureBase64: string
  Signature produced by the signing address
- useStrictVerification: boolean = false
  If true, apply strict BIP-137 verification and enforce address flag verification; otherwise, address flag is ignored during verification
Returns boolean
True if the provided signature is a valid BIP-322 signature for the given message and address, false if otherwise

Throws
If the provided signature fails basic validation, or if unsupported address and signature are provided
