Epson Projector - Add Support for Projectors Requiring Authentication

It looks like the current Epson projector integration works with projectors that don’t require a username and password for control via network. For projectors that do require login, HA returns an unknown error. The error log shows an error 401 was returned - authentication error.

It would be nice to be able to specify a username and password in the setup sequence if a projector requires it.

I have hit this same problem today with my EH-TW750.
