We introduce Taproot support in the test framework through a global toggle. A few modifications are made to some tests to adapt them under Taproot (notably the hardcoded fees / amounts). This is based on my introduction of a quick and dirty support for TapMiniscript in my python-bip380 library: https://github.com/darosior/python-bip380/pull/23. In addition to this i didn't want to implement a signer in the Python test suite so here we introduce a simple Rust program based on our "hot signer" which will sign a PSBT with an xpriv provided through its stdin and output the signed PSBT on its stdout. Eventually it would be nicer to have a Python signer instead of having to call a program. The whole test suite should pass under both Taproot and P2WSH. Only a single test is skipped for now under Taproot since it needs a finalizer in the test suite. I also caught a bug in the RBF tests which i fixed in place.
A quick and dirty program to sign Taproot PSBTs with a given xpriv. This reuses the hot signer Rust code so i don't have to reimplement everything in Python.
