maxlen was confusingly named. maxlen referred to the static size of the
entire packed log. instead, the maxlen of the current item should be
passed to zero_pad.
bytearrays are padded to ceil32(runtime_len), not ceil32(maxlen).

This fixes the issues that I reported, and will unblock the deposit contract verification.

LGTM, @charles-cooper anyway that we could've picked this up in a test?

@jacqueswww yeah maybe, I think if there was data in the next cell whose first byte (BE) was nonzero then it would have been corrupted.
