sunshine can't execute commands while disconnected

[psychosispy]

When using Sunshine to connect and exit streaming, commands can be executed to change the server display, such as switching resolutions and locking the screen. However, these operations cannot be performed upon disconnection. This results in having to perform the disconnect and stop streaming operations twice on the client side to restore the server to its normal display mode, which can be inconvenient.

Possible solutions: Add an option on the server to automatically stop streaming upon disconnection, or add the ability to execute commands upon disconnection.
