Support for custom Certification Authorities and Client Certificates

[Steven--]

Thank you for this great app.

Would it be possible to add support for custom CAs and client certificates?

Both the CA certificate and the client certificates are properly imported in Android (under Settings > Security > Encryption & Credentials) and work in other apps that support them, but they do not seem to work in Chora (at least when used simultaneously, I didn't test with a custom CA and no client certificate).
