Release v0.8?

[tsbinns]

Since v0.7 released in June there've been quite a lot of changes, mostly with the GSoC work: https://mne.tools/mne-connectivity/dev/whats_new.html
Also with #223 merged, all the major goals of the GSoC project were met. I'm wondering if it's worth cutting a release for v0.8 soon?

#232 is related to the GSoC work and should be near finished, however it requires the unreleased MNE 1.10 (which will presumably be a while). I imagine it would be bad form to have a release relying on MNE dev branch features. Is it worth holding off on merging #232 until MNE-Conn v0.8 is released?

Looking at the open PRs, I think #257 is ready. #266 was paused pending the upstream MNE changes but that's sorted now in v1.9, so perhaps that could also be included.

Would also need to be sure to update CITATION.cff info (#229)
