Allow deletion of views via the UI

[K-Meech]

For #1148

This PR allows deletion of views via right clicking in the MoBIE viewer and selecting Delete View. Similar to the view saving options, it allows deleting views from the 'current project' (i.e. the dataset.json) or an 'external file' (any view .json saved on the file system). The 'current project' option is currently only implemented for local projects - if you try to use it with a github / s3 project it should throw an error.

Let me know if any changes are needed! I tried it out locally with a few example projects, but it would be great if more people could test this out to check everything is working correctly 😄

Hi @K-Meech, I don't manage to locally check out your PR.
Would you mind doing this PR from a branch within this repo rather than from your fork?

[K-Meech]

I think you can checkout the PR locally with:

git fetch origin pull/1193/head:test-pr-1193
git checkout test-pr-1193

Does that work?

[tischi]

Yes, thanks!

@K-Meech I made a branch test-pr-1193 where I added an error message if the dataset.json is not found. The issue is that there are now many other ways of opening MoBIE that do not include a dataset.json.
The clean solution would be to not even show the "Delete from current project" option.
I was a bit in a rush right now. I think I would still try to implement this rather than throwing the error...

Hi @K-Meech,

Shall we just merge? Including my additions (see above)?

[K-Meech]

Sounds good to me - go ahead @tischi !
