`Only Supports Older Hardware Wallets

The lack of PSBT support means that modern hardware wallets with high quality airgaps such as Keystone and Specter-DIY are not yet supported. Properly verifying a receive address is only possible for advanced users and also requires plugging your hardware wallet into your computer, adding another potential attack vector.

I planned on making a pull request because Casa supports Keystone, but it looks like it was already removed in the casa.md file.
