Pass Declare Nonce to Starknet CLI

[solimander]

Usage related changes

This PR fixes the following error when passing a custom nonce to a declare transaction via the Account class:

Signature (..., ...), is invalid, with respect to the public key ..., and the message hash ...

This would occur because the message hash with the custom nonce would be signed, while the transaction would be created with the current account nonce. This issue made it nearly impossible to submit multiple declare transactions at the same time.
