Add support for non-standard packed mode

davesque commented 6 years ago

What was wrong?

See issue #67 .

How was it fixed?

Added registry_packed registry for packed mode encoders. Added packed mode encoder classes. Added encode_single_packed and encode_abi_packed functions.

@pipermerriam Yeah, it was pretty straight forward. The tests were the hardest point as you allude to. The thing that probably seems most confusing is that little utility function words. To keep you in the loop, my goals with creating that were:

To have a way to describe the expected results of encodings without using Python's very verbose literal byte syntax
To avoid having to literally spell out all padding bytes (of which there are many with 32 byte wide words)
To be able to use more or less the same encoding "description" for both standard and packed mode

Ugh. Accidentally clicked the close button. I wish Github had a confirmation dialogue for that or something :/.
