Allow manually specifying whether a paymaster output is required

[ShookLyngs]

Description

Currently the @rgbpp-sdk/btc checks whether the CKB_VTX has included sufficient capacity in its inputs. If it does, the transaction is marked as needPaymaster = false, otherwise a payment output is generated for the paymaster.

However, In some cases, the paymaster output in the BTC_TX is requested to be NOT NEEDED:
