Upgrade rust-bitcoin to 0.32

[notmandatory]

Describe the enhancement

The LDK team would like to use rust-bitcoin version 0.32 so BDK should update too. To do so we also need to update the following crates to the versions that depend on rust-bitcoin 0.32:

• rust-miniscript
• rust-bitcoincore-rpc
• bitcoind
• electrsd
• rust-electrum-client
• rust-esplora-client
• rust-hwi

Use case

Updating to rust-bitcoin 0.32 removes the need for a specific no-std feature, it will be implied by not enabling the std feature. It also includes a new io crate.

I'm willing to give a try on this one.

Thanks @oleonardolima you'll need to keep an eye to see when rust-miniscript and rust-bitcoincore-rpc are ready. Feel free to start making PRs for any of the crate that only need rust-bitcoin updated to 0.32.

Another thing this PR should fix is the broken docs.rs for bdk_persist. I think they're breaking because it doesn't build with default features.

Sure, I'll keep an eye and initially start from other crates.

Cool, I'll check if it solves the docs once the PR is done.

@notmandatory Would #1423 fix the docs.rs fail? - Oh I see you mentioned it wouldn't be needed after the rust-bitcoin upgrade. Still maybe a quick fix in the interim
