API Sign in support using session key

[seth-rah]

Is your feature request related to a problem? Please describe.
Would it be possible to allow sign-in using session key similar to Chatterino?

Describe the solution you'd like

Best to describe using pictures of what Chatterino does already

Additional context
This should solve the issue with sign-in captcha requests on the user and is usually refreshed once a month I think

I am presuming Chatterino is allowing user's to manually paste their session token from their browsers?

From the looks of it yes

It just provides a frontend interface that allows you to copy that session token, so that you can paste it in app
