Adopted lazy geometry encoding

- LFSR_TAG_GEOMETRY ---> lfsr_data_fromgeometry

Not much to say about this one, LFSR_TAG_GEOMETRY is a bit of an
outlier.

I did consider deduplicating with the mptr encoder, but decided that
would be too hacky, and create problems for future metadata redundancy
things.

Still saves code though, which is nice:

           code          stack          ctx
  before: 35632           2440          636
  after:  35580 (-0.1%)   2440 (+0.0%)  636 (+0.0%)
