BIP-0158: add test cases for OP_RETURN with op codes, empty filter

Browse Source 
In this commit, we add a new test case for a filter built from a block
that has a transaction with an OP_RETURN which isn't followed by only
push data items. The prior implementation for btcd (which was used to
generated these test vectors), had a stricter check which caused it to
add extra items to the filter. We also add a case of a block that has a
single coinbase transaction, with that transaction having only an
OP_RETURN output. As a result, that filter will be "empty", and is
signalled by by a single zero (0x00) byte.

In order to make building the code that makes the test vectors
reproducible, we've added go.mod and go.sum files as well.
