Function deriveChildPublicKey

deriveChildPublicKey(
    rootUncompressedPubKeySEC1: `04${string}`,
    predecessorId: string,
    path?: string,
    chainId: string,
): `04${string}`
Derives a child public key from a parent public key using the sig.network v1.0.0 epsilon derivation scheme. The parent public keys are defined in @constants.ts
Parameters
- rootUncompressedPubKeySEC1: `04${string}`
  The parent public key in uncompressed SEC1 format (e.g. 04 || x || y)
- predecessorId: string
  The predecessor ID is the address of the account calling the signer contract (e.g EOA or Contract Address)
- path: string = ''
  Optional derivation path suffix (defaults to empty string)
- chainId: string
  The chain ID for key derivation
Returns `04${string}`
The derived child public key in uncompressed SEC1 format (04 || x || y)
