Use better binding transformations where possible (#141)

* Use better binding transformations where possible

`Binding.init(get:set)` is handy but buggy when it comes to preserving
animations and passing in the correct transaction. We can preserve the
binding's transaction in a less buggy manner by leveraging dynamic
member lookup instead, a trick we've employed in TCA, but never here.

Add `HashableObject` protocol (#133)

SwiftUI's built-in navigation tools requires hashability and
identifiability of objects, and while objects get identity for free, we
must manually equate and hash objects by their object identity. Instead,
the library can vend a protocol with default conformances.
