Coordinated releases with algaeff 2.0.0

[favonia]

@jonsterling proposed a plan to coordinate releases in #24 in the face of the next major release with breaking changes. Let's continue the conversation here.

• asai: fix: use algaeff 2.0.0 asai#132
• yuujinchou: fix: use algaeff 2.0.0 yuujinchou#123
• forester: ?

[favonia]

@jonsterling algaeff 2.0.0 and yuujinchou 5.2.0 are ready! So potentially you could start updating forester now...

[jonsterling]

Thanks @favonia ! I'm cutting a new version of forester that adds the upper bounds, and then once your new packages appear on opam I will upgrade forester.

[favonia]

@jonsterling I thought you can just update the existing OPAM files in the OPAM repository and maybe that would be easier (?) Actually, this might not work well.... because OPAM might use older forester as a "solution"? (I'm not sure what would happen.)

[favonia]

@jonsterling Actually, I have perhaps a better plan: I have figured out how to release multiple packages at once. I can release all four OPAM packages when you are ready.

[jonsterling]

Cool :) If you can wait until my PR is merged (ocaml/opam-repository#24735), then I will be very happy

[favonia]

Now the coast in clear but I want to release everything with asai 0.3.0 altogether!

Done by ocaml/opam-repository#24738.
