Update pfile format

[mattgodbolt]

Maybe something like YAML?

We should tests we can losslessly roundtrip the new format and compare it back with the original old format.

This would be the basis for some "extended" content in pfiles for some new features....

[mattgodbolt]

YAML seems a good fit. Just tried hand-converting a bit of a mismash of my own pfile and a basic one:

things like containers fall out naturally, and we can use comments to make them somewhat human-parseable.
