Add UITextView.valuePublisher

[freak4pc]

This PR adds support for a UITextView.valuePublisher publisher based on the one in RxCocoa and NSTextStorage (based on @jdisho's delegate proxy support).

Closes #19

Uhm this works fine under Xcode 11 but crashes in 12.

@jdisho any thoughts before I dig into it? :]

[jdisho]

Hmm.. interesting 🤔
I will have a look into this @freak4pc

[freak4pc]

Thanks a ton @jdisho ❤️

[jdisho]

Can this wait a bit more? I've been quite busy recently 😔

[freak4pc]

Generally, sure, but I’m waiting on this to release a version because I don’t want to cut a release that’s crashing potentially :P Thank you very much. Shai

@jdisho sorry for pinging all the time, I know how busy you are :) Just want to make sure you remember it ^_^

@jdisho I believe I've mostly resolved this. The crash was resolved in Xcode 12 GM, but for some reason you've sent a .finished event on the subscriber whenever a single event was published.

This was masked by the tests, but in reality these publishers are "infinite" (should only send completion on deallocation of the delegate).
