Read/write based on realm

@calisro

the realm in the passwd files

The htpasswd files I'm familiar with don't have a realm

Are you using an htdigest file?

@calisro

Without this, I’m currently forced to run multiple rclone instances on different ports specifying the ‘read-only’ flag is the remote itself and directing the different users to the different ports.

Neat work-around
