[Feature Request] Run maestro on multiple devices at the same time on a single computer

[jimingzhi]

Is your feature request related to a problem? Please describe. A computer can only run one maestro even if there are multiple devices connected, and if i want to run multiple maestro, i need multiple computers, which is a waste of resources.

Describe the solution you'd like Run maestro on multiple devices at the same time on a single computer. If multiple devices are connected to the PC, run the ‘-device’ command to select a specific device to run the maestro on.
