Add JOSS paper

[ml-evs]

Hi @CasperWA, @shyamd & @markus1978. Here is a skeleton for JOSS, as discussed in #203. I will try to turn this into a proper draft when I get time, but feel free to comment on the proposed content/structure. I think there is still some discussion to be had in #203 about authorship, so let's continue that over there.

You can now see the preview of the paper in the build artifacts of the CI.

Hi all, I think this is now in a shape where it can usefully receive feedback. It would be great to polish and submit during the workshop to cut down on the back-and-forth. Look forward to speaking to you all next week.

I've only chucked the figure in to make it more interesting, I will have to update it as part of my tutorial on Monday anyway, so will see what I can come up with...

@dwinston @CasperWA @markus1978 @fekad @shyamd

I suggest changes via #840

[ml-evs]

Some updates:

• Removed figure after discussion with @CasperWA (i.e. me telling him I was doing it)
• Turned some bibs into inline links where no bib reference is available, e.g. MongoDB.

[ml-evs]

After @fekad has taken a look and added his details, I will aim to submit this paper early next week.

We will then have some amount of time in pre-review where we can still make any minor changes (but please do raise any issues before then).

[ml-evs]

I am submitting this now, and will tag your GitHub accounts in the review. We can still make tweaks on this branch directly (and it will be good to fill out our online docs as suggested in the other PRs).
