IOS CI and Ability to distribute to single platform

[jigar-f]

• Implemented CI for ios, Ability to distribute IOS to test flight
• Added a way to push any single platform if we want

If you put out a tag like this, It will push out the build for all platforms including desktop, android, and ios
git tag -a "lantern-7.0.0" -f -m "Tagging production release"

But if you want to put it out just for ios, this will put on a new test flight build for only IOS
git tag -a "ios-lantern-7.0.0" -f -m "Tagging production release"

For desktop use
git tag -a "desktop-lantern-7.0.0" -f -m "Tagging production release"

For android use
git tag -a "android-lantern-7.0.0" -f -m "Tagging production release"

Also, it will respect beta, production, and internal tags just as before

I'm gonna merge this since I want to put out a new 8.0.0 beta build and want to incorporate these changes first. Great work on this, @jigar-f!!
