Support for IP based controls for MadVR Envy

Supports real time notifications and commands

Command structure follows the same in the manual https://madvrenvy.com/wp-content/uploads/EnvyIpControl.pdf?r=112a

For things that take values, use a comma -> ["KeyPress, MENU"]

Not every single command is implemented, such as submenus or changing complicated options. You can use commands for all the typical stuff the remote can do.
