Hi @TheCedarPrince I started working on this, it would be nice if you could merge this PR so we have CI working or give me merge access and I can do it myself.

It is not finished yet but just so we can set up some initial stuff it should be good to go, test locally and it works.

I did not know this but since it is not running here CI runs on my fork! So no rush at all!!

[TheCedarPrince]

Hey @gpucce , you should now have access to all the things!
Sorry about that!
I thought the @JuliaAnimators/maintainers team has at least maintainer rights by default.
Before we merge this, something I noticed was that accidentally included in this PR was the live streaming functionality.
This is quite different from the JavisViewer and needs to not be merged here...
Not sure where to put the streaming functionality just yet but we should at least keep it back inside of Javis.jl itself.

[TheCedarPrince]

I can give more of a review later - right now, quite tired!

[gpucce]

I was going to ask you if you wanted to move the streaming as well, that I will move back then!!

[Sov-trotter]

I think streaming is pretty much basic so better to keep it in base Javis. In the future I am thinking of having such features out of base(in a JavisExtensions package).

Hi @TheCedarPrince this should be the JavisViewer package! If you can review it and let me know if smth is missing i will add it!
