Add crates to README

[ValuedMammal]

Suggestions for adding more notable libraries/projects to the organization README

• bdk-kyoto (bip157)
• bdk_sqlite
• bdk_redb
• bdk-wasm

[notmandatory]

@110CodingP would you consider bdk_redb stable enough (ie. no big API changes expected) to put in the community/stable section of the README page?

Not yet 😅 , I am yet to incorporate redb 3.0 and also wanted to do some cleanups.
