Dunai 0.12.2, dunai-test 0.12.2, and bearriver 0.14.7

[ivanperez-keera]

Hi everyone! I'm happy to announce release 0.12.2 of dunai. It is accompanied by a matching release of dunai-test and bearriver.

The main changes are:

• Add missing version bounds to packages.
• Fix version bounds on transformers.
• In bearriver, we now provide matching FRP.BearRiver.EventS (akin to Yampa's), and some definitions have moved to FRP.BearRiver.Hybrid.

As always, this release comes exactly 2 months after the prior release. Feel free to try it, and open new discussions for any issues you see.
