Respect --nonce and --block-hash arguments to allow signing transactions in offline

[frol]

Currently, --nonce and --block-hash CLI arguments seem to be ignored in all the signing options.

Lines 15 to 18 in 48cb8fc

	pub nonce: Option<u64>,
	#[interactive_clap(long)]
	#[interactive_clap(skip_default_input_arg)]
	pub block_hash: Option<String>,

near-cli-rs/src/transaction_signature_options/sign_with_access_key_file/mod.rs

Lines 59 to 62 in 48cb8fc

	let current_nonce = rpc_query_response
	.access_key_view()
	.wrap_err("Error current_nonce")?
	.nonce;

near-cli-rs should not make any calls to RPC when nonce and block-hash is specified, so it will work on computers that are not connected to the Internet.
