amazing, good ol' pymultinest installation error is back

[sahiljhawar]

@mcoughlin any suggestions for pymultinest on ubuntu?

[mcoughlin]

Not beyond raising an issue on their GitHub. Worked be great to drop it as a mandatory dependency

[sahiljhawar]

This is not a pymultinest issue as far as I can see, it is due to pytest-asyncio. I am able to reproduce and mitigate this locally, but the solution is not working on Github Actions. Tried looking on bilby's Actions, their tests are passing.

I am merging this to reflect the keras changes, CI issues will be dealt later on, refer #393
