Open window size with the remote resolution

[Transis-Felipe]

When the display settings are configured to use Original scale, would be nice to open window with the same size as remote resolution

Today it open every new window with the same size (the last one used)

Eg.: Remote pc has 1920x1080, the new window should be created with this size.

The image below show two connections. Every window opened will have the same size.

Would be nice to have an parameter size:

rustdesk --connect <PEER_ID> --size 1920x1080

rustdesk --connect <PEER_ID> --size Auto to adjust the window automatically when the window is opened
