073ff81536 address: Simplify `Address::assume_checked` impl (Max Fang)
e4cf8ebc20 address: Add `Address::into_unchecked` (Max Fang)
Pull request description:
## Commits
### address: Add `Address::into_unchecked`
Adds an ergonomic way to convert any `Address` (network can be checked
or unchecked) into an `Address<NetworkUnchecked>` without cloning, which
I've found useful in several contexts.
### address: Simplify `Address::assume_checked` impl
Removes an unnecessary `match` which I noticed while implementing `Address::into_unchecked`.
## Small note on use of `Self`
The style guide in `CONTRIBUTING.md` notes to return `Self` when possible, but that doesn't apply here as the `Address` being returned is different from the `Address` type referred to by `Self`, due to the changed `NetworkValidation` type.
