Dunai 0.13.0, dunai-test 0.13.0, and bearriver 0.14.9

[ivanperez-keera]

Hi everyone! I'm happy to announce release 0.13.0 of dunai. It is accompanied by a matching release of dunai-test and bearriver.

This is a major release that introduces an alternative definition of the ListT combinators that uses the list-transformer library instead of the traditional definition from transformers, which had been deprecated and eventually removed.

The new definition is governed by a flag list-transformer. When enabled, dunai will depend on the list-transformer library and use that variant of the combinators. The flag has been made automatic so that it'll be enabled if a version of transformers greater than 0.6 is needed (which is the default with modern GHCs). I expect this to offer a smoother installation path for most users.

As a consequence of this change, using the combinators for the old ListT from transformers is also deprecated in dunai. We recommend all users to switch to the variant from list-transformer. The old interface will be removed in future versions.

Apart from that, this release also provides a matching FRP.BearRiver.Hybrid (akin to Yampa's). This is one more step towards providing a 100% match in bearriver for all definitions in Yampa.

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