Subject: [PATCH] tests: add BIP352 test vectors as unit tests

Use the test vectors to test sending and receiving. A few cases are not
covered here, namely anything that requires testing specific to the
wallet. For example:

* Taproot script path spending is not tested, as that is better tested in
  a wallets coin selection / signing logic
* Re-computing outputs during RBF is not tested, as that is better
  tested in a wallets RBF logic

The unit tests are written in such a way that adding new test cases is
as easy as updating the JSON file
