I need one or two functions:
* most importantly, a function
that tells me if a keyword names a valid encoding, and if so,
returns a proper value to pass as an :external-format.
* optionally, a function to return the list of all available encodings;
maybe taking a keyword argument that allows to distinguish between
actually loaded vs potentially available encodings.

I suppose that can do for now. This currently happens in a system called
asdf-encodings that is separate from ASDF. This stricture is a good reason
to keep it separate and not merge it into ASDF as was suggested.
If you define an API, I'll change asdf-encodings to use it,
and that won't count as a reason against merging asdf-encodings into
I don't want to do a merge before asdf-encodings is stable, anyway.

Thanks for the pointer.
