Request to add configuration inside the root .ocamlformat file

[mbarbin]

Hi!

In the process of doing things in #37 and I thought it would help if you wanted to pin down what ocamlformat configuration you'd like for the project. This would make editing files simpler! At the moment I'm careful not to change the formatting on save, because this file is blank, which is ironic for a project that actually enables ocamlformat!
Thanks!

Perhaps something like:

.ocamlformat

version=0.28.1
profile=??? # (conventional | janestreet)
parse-docstrings=true # or not?

Indeed that is strange! Seems like anything stable would be better than nothing: do you have a preference?

I proposed something in #40 and we can review the details in the PR while looking at the resulting formatting diffs. Thanks!
