Merge bitcoin/bitcoin#23253: bitcoin-tx: Reject non-integral and out of range int strings

Browse Source 
fa6f29de51 bitcoin-tx: Reject non-integral and out of range multisig numbers (MarcoFalke)
fafab8ea5e bitcoin-tx: Reject non-integral and out of range sequence ids (MarcoFalke)
fa53d3d826 test: Check that bitcoin-tx accepts whitespace around sequence id and multisig numbers (MarcoFalke)

Pull request description:

  Seems odd to silently accept arbitrary strings that don't even represent integral values.

  Fix that.
