fa275e1539 test: Fix intermittent feature_taproot issue (MarcoFalke)
Pull request description:
The nodes might disconnect (e.g. due to "Timeout downloading block" https://cirrus-ci.com/task/5313800947630080?command=ci#L1763) and the test fails to continue.
Fix that by reconnecting the nodes.

The "whitelist" and "connect_nodes" is not needed in feature_taproot.py,
so remove it.
The changes to key.py are required when running the unit tests from the
test folder. Failure on current master:
[test]$ python -m unittest functional/test_framework/key.py
.E

This adds a --dumptests flag to the feature_taproot.py test, to dump all its
generated test cases to files, in a format compatible with the
script_assets_test unit test. A fuzzer for said format is added as well, whose
primary purpose is coverage-based minimization of those dumps.
A large functional test is added that automatically generates random transactions which
exercise various aspects of the new rules, and verifies they are accepted into the mempool
(when appropriate), and correctly accepted/rejected in (Python-constructed) blocks.
Includes sighashing code and many tests by Johnson Lau.
Includes a test by Matthew Zipkin.
Includes several tests and improvements by Greg Sanders.
