Add elm-deps as dependencies

[robinheghan]

Git deps might have direct and indirect dependencies which aren't git-dependencies. These should be added to the right places in the application's elm.json.

Not entirely sure how this should work. Do we clone the repos and read their tags, scrape package.elm-lang.org? Needs investigating.

I ran into an issue where I installed a git-dependency but my app failed to compile due to missing all the dependencies for that package. At first I thought this was a bug but if I understand correctly that's what this issue is referring too?

@MartinSStewart Yes. Not sure how to best approach this issue. I don't think elm install supports specifying a version range, if it did it would be a simple matter of iterating through all dependencies in elm.json and calling elm install on them 🤷‍♂️

[MartinSStewart]

What about using elm-json instead?

[robinheghan]

That could work. I do have limited capacity at the moment however. A PR would be much appreciated if you have the time.

[MartinSStewart]

I can take a look later today and see if it's something I can puzzle out.

[robinheghan]

Awesome!

Sorry, I won't have time to do this either. Maybe someone else can implement this or maybe I'll give it a shot at a later date.
