test_to_address_size()

Documentation for tests/frontier/validation/test_transaction_rlp.py::test_to_address_size@49633827.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/frontier/validation/test_transaction_rlp.py::test_to_address_size --fork Amsterdam

Encode the to field with a truncated 19-byte address or a 21-byte address made of a zero byte prefixing a valid address.
