Add support for http basic auth

[pmaziere]

1. Environment

• Device: samsung A5
• OS: lineageos 18.1
• APP: 0.9.12

2. Describe the feature request

Since http basic auth does not seem to be supported by the UI, I tried the standard way of defining a user and password for http basic auth in the server URL field such as:

https://user:password@freshrss.example.com/api/greader.php

I receive the "unauthorized for CL token" message.

I guess this is because http basic auth is not yet supported, neither by the UI , nor by the library used to parse or connect to the server URL

Could the http basic auth feature be added to Read You ?

Thanks
