track(event:properties:) takes [String:Any], but screen(screenTitle:properties:) takes [Any:Hashable]

[JetForMe]

Describe the bug
There's a bit of mismatch/asymmetry between the various track and screen methods. Namely, track(event:properties:) takes [String:Any], but screen(screenTitle:properties:) takes [Any:Hashable]`.

Expected behavior
I'd expect these to take the same thing, unless there's some reason they can't.

Platform (please complete the following information):

• Library Version in use: 1.0.2
• Platform being tested: [e.g. iOS]
