Update to use bdk_wallet 1.0.0

[notmandatory]

Describe the enhancement

This project is overdue for an update to use the latest and greatest bdk_wallet 1.0.0. This will be the tracking issue for this update plus some other refactoring and feature enhancements needed for this app.

• Update to bdk_wallet, remove sled support, change rust version to stable
• Support chain data clients: electrum, esplora, rpc, kyoto (CBF) in same binary
• Add page in book-of-bdk for how to install and use bdk-cli

Use case

I'd like this project to be a tool for manually testing bdk_wallet and training new devs how the bdk_wallet APIs work in a simple CLI app.

Additional Context

The bdk repo already contains a simple cli using the bdk_chain crate, but it is only meant to be an example and not a supported app.
