Conflict with existing original packages

[nekketsuuu]

Currently, packages distributed by this repository have version suffix +satysfi. It is OK if these packages are compatible with the original packages. However, some packages already break the compatibility.

So we should rename our forked packages in order to make no conflict with existing packages.

To proceed this, more communication between maintainers of the original libraries and us may be needed. See ocaml/opam-repository#13439.

I’m strongly 👍

It’s getting extremely tough for me to write code supporting versions of upstream YoJson and its SATySFi fork.
