fix: pop call with composite types

[moliholy]

Closes #689.

This PR allows to properly query keys with composed types by transforming them into tuples.

You can test it out by running:

pop call chain --pallet Hrmp --function HrmpChannels --args "1000" "4566" --url wss://rpc.ibp.network/paseo

OR

pop call chain --pallet Hrmp --function HrmpChannels --args 1000 4566 --url wss://rpc.ibp.network/paseo

OR

pop call chain --pallet Hrmp --function HrmpChannels --args "(1000,4566)" --url wss://rpc.ibp.network/paseo

OR

pop call chain --pallet Hrmp --function HrmpChannels --url wss://rpc.ibp.network/paseo

And manually typing 1000 and 4566 as parameters.

Since I was on it, I also:

• Fixed the way storage data is printed out in the terminal.
• Placed the logic to ask for a new call governed solely by the --skip-confirm flag, which is more specific.
• Included --skip-confirm in display().

@AlexD10S there's still an edge case: if the second parameter is not specified, it does not return anything. I believe this is expected, as the key is composite. Actually, polkadotjs does not return anything either. But of course this is subject to further discussion.

Amazing!! Thanks for fixing this
