Idea: using YAML instead of TOML

[refi64]

Kind of like shards does. It's quite a bit more concise than TOML and even looks kind of Python-y.

I know the answer to this is probably going to be "big change, not enough gain", "conciseness isn't a good reason to switch", "harder to parse", etc...but I figured this still is worth a shot. ;)

toml is being used by other packaging standards in python, so we're sticking to it.

eg TOML was picked in PEP518 - see the discussion there for reasons:
https://www.python.org/dev/peps/pep-0518/#other-file-formats

I don't see it argued anywhere that maybe using an unfinished standard, such as TOML, might pose a problem long term.

I'd rather have it support both.
