Would be good to get a specification and perform a crosswalk

The format is documented here https://github.com/riggsd/guano-spec/blob/master/guano_specification.md

It's all broadly compatible - very easy to map onto AC and DwC, and we might consider whether some of their terms might be adopted (e.g. their "Filter HP" and "Filter LP" seem useful).

Their "time-expansion (TE)" field is somewhat related to ac:mediaSpeed: one is the reciprocal of the other, though note that their TE is constrained to integer values.

Notes from 2024-02-20 working session:

We intend to incorporate "Filter HP" and "Filter LP" into avcore, and will take this forward. See #264
The relation to time-expansion is already documented in the term notes
