Support for first party Combine framework

[edorphy]

A great enhancement would be to refresh this library with Combine.

Absolutely! Need to maintain backwards compatibility for a while, but we'll get there.

Following up:

Combine Availability:
iOS 13.0+
macOS 10.15+
Mac Catalyst 13.0+
tvOS 13.0+
watchOS 6.0+

I will look into a v2 of this library this fall with Combine instead of Signals with the release of iOS 14 and macOS 11.

Any updates? I'm writing my own lib and putting @published properties all over the place and it works out nicely.

Still keeping an eye on this. Now that iOS15 is out I will start a V2 branch where we can work on Combine support.
