WIP

Get simple OP_1 functional test case working

Get tests for arithmetic and comparison opcodes working

Get all functional tests passing

Rename test case to Arithmetic64bitTest

Rename file to feature_64bit_arithmetic_opcodes.py, add it to test_runner.py

Get tests passing in feature_taproot.py

Remove unused push_le4

Revert test fixture setup

Cleanup

Fix linting
