OAuth2 Mechanism Support

[genvmoroz]

Hi there, have you planned to implement OAuth2 mechanism for this library?
I'm looking forward to use github.com/emersion/go-imap/client IMAP client to get access to outlook.com using oauth2, is it possible for now? If not, do you have a plan to integrate it? If yes, when do you expect to integrate it?

Thanks in advance!

outlook.com uses a non-standard mechanism. OAUTHBEARER is the standard, but Microsoft only supports XOAUTH2.

@emersion thank you, so that means your client does not support the oauth2 mechanism for outlook.com? Or is there some way to hack the system?
