Feature request: Print raw Tx

[amanusk]

It would be very useful to have an option to print out the raw transaction without broadcasting it to the network.
For example, to compare a possible future transaction with an existing transaction on the network, and see the difference.

Example:

[~/Code/Starknet/starkli]> starkli invoke eth transfer 0x5465aa79114f0415f95100cafeb4640b17bce2653810903738ac6c1a7694b6c 100 0 --raw-tx

Yeah I was thinking about this exact feature at some point.
