Bump version and dependencies post ndarray 0.14

[xd009642]

For a quick release to coincide with ndarray 0.14. Also bumped all other deps since they required no code changes

Fixes #69

Looks good to me 👌
As evident, I don't have much time lately to dedicate to ndarray-related projects. I transferred ownership of ndarray-stats to the release team in the rust-ndarray org - I think you are best placed when it comes to choosing who should be part of it @bluss.
I am happy to cut this release though if necessary.

Travis needs update to build with 1.42 as min version.

I don't have much time for Rust either, unfortunately :( So we are looking for maintainers here

[xd009642]

Done, I also simplified the tarpaulin install as the rust flag isn't needed anymore now proc macro is stabilised 😄

EDIT: Also don't forget I'm willing to be a maintainer 😉

@LukeMathWalker What do you think, we can welcome @xd009642 to be maintainer of ndarray-stats and ndarray?

[LukeMathWalker]

He has been around for a long time, he knows and uses both projects professionally, I know where he lives if he pulls anything funny - I think we can welcome him 😁

aha I have power now 🙃. Does anyone have any issues if I take a look at #63 and merging it before we push out a new release? I was having a read and it all looks pretty good to me, not sure why it's in draft

[bluss]

Also, join #rust-sci:matrix.org on matrix if you want to. It is not a lively place, but it's the place we have I think

[xd009642]

I'm going to merge this as I can now 😉
