make ios scrcpy run in linux

[wanliLiu]

currently ios device detect use lib ios-device-lib, and this lib can only run in mac or windows,not run in Linux. as for run xctest use appium default way xcodebuild, so , all of this lead to cannot run in linux.

and this lib tidevice can fix it, use tidevice list fix ios device detect, and run xctest use tidevice xctest -B com.facebook.wda.WebDriverAgent.Runner, thus ,because it wirted in python, so it can run in mac windows and linux. I have done all of this in this project,it works,

by the way, video stream use mjpeg
