bitcoin: Bump version to 0.32.0-rc1

In preparation for dropping the first release candidate bump the version
and add a changelog.

Please not I went to much more effort that usual with the changelog,
open to review on the overall form - not promising I'll change it but
definitely would like to keep iterating and improving.

If this changelog is appreciated then FWIW I don't think we should
bother automating it, a machine does not have all the context required
to create it.

+
+## Changes to and involving the `Network` type
+
+In release 0.31.0 we managed to annoy a lot of people by the addition of `non_exhaustive` to the
+`Network` type. After much discussion, and in an effort to cater to multiple camps, we did a bunch
+of changes this release. To sum up, "network" is ill defined and it means different things to
+different devs/software. Your software should probably have some custom handling of whatever
+"network" means to you.
+
+In particular consider having some type that implements `AsRef<Params>`, we have attempted to
+ replace `Network` in much of the API ([#2541](https://github.com/rust-bitcoin/rust-bitcoin/pull/2541)).
+
+- Add `NetworkKind` [#2232](https://github.com/rust-bitcoin/rust-bitcoin/pull/2232)
+- Reduce usage of `Network` in the public API [#2541](https://github.com/rust-bitcoin/rust-bitcoin/pull/2541)
+- Remove `Network` from `AddressInner` [#1832](https://github.com/rust-bitcoin/rust-bitcoin/pull/1832)
+- Add consts to `Params` for individual networks [#2396](https://github.com/rust-bitcoin/rust-bitcoin/pull/2396)
+- Add `params()` method to `Network` [#2172](https://github.com/rust-bitcoin/rust-bitcoin/pull/2172)
+- Use `KnowHrp`` instead of `Network` [#2387](https://github.com/rust-bitcoin/rust-bitcoin/pull/2387)
+- Add check to max difficulty transition threshold [#2337](https://github.com/rust-bitcoin/rust-bitcoin/pull/2337)
+
+## Other API additions
+
+- Add `CompressedPublicKey` [#2277](https://github.com/rust-bitcoin/rust-bitcoin/pull/2277)
+- Add a `consensus::deserialize_hex` function [#2039](https://github.com/rust-bitcoin/rust-bitcoin/pull/2039)
