ember-cli-typescript upgrade

[elwayman02]

We're getting dependency lint errors because this addon depends on ember-cli-typescript 2.x, while other addons rely on 3.x or even 4.x. Can this package be upgraded to a newer version of ember-cli-typescript?

[runspired]

the presence of ember-cli-typescript may troll ember-cli-babel, preventing the use of enableTypeScriptTransform when <2.x (which this brings) is present.

Can we still upgrade this? It doesn't seem to build anymore because it's asking for a version of ember-cli-typescript that isn't apparently available...

this could be closed as #306 landed!
