Create a bdk_floresta chain source crate

[evanlinjin]

Describe the enhancement

The Floresta project uses technologies such as Utreexo, softchains and CBF to make integrating a full node in a wallet as easy as connecting to someone else's node. It's almost a no-brainer to support such magic in BDK.

According to @Davidson-Souza, if we make use of the foresta_wire and floresta_chain crates, it will be enough to create a revolutionary chain-source crate for BDK!

Let's start the discussion with the ticket.

Use case

Are you kidding me?

Documenting that, after a brief talk with @Davidson-Souza, Floresta has already a watch-only wallet on LibFloresta and for this issue that could be useful as a starting point.

I`m already working on Floresta and contributing to bdk was already on my plans.
I'd appreciate if i got assigned to this issue.

@jaoleal thanks for reaching out! Sure, I'll also provide a few pointers here and there (at some point). Sorry, been quite busy with the other work.
