Use device by reference for dino

[light-and-ray]

Hello! I tried to temporary override global device variable in my extension, which uses your extension, before use dino model, to make it works on cpu, for Intel ARC witch doesn't support 64-bit float, and for potato-gpus which doesn't have enought memory for dino model. But I've found the extension copies device on app started. from ... import variable copies it

restore = []
try:
    if useCpuForDetection():
        oldDevice = devices.device
        def restore_():
            devices.device = oldDevice
        restore.append(restore_)
        devices.device = 'cpu'
        print(f'[{EXT_NAME}] Use CPU for detection')
    self._createMasks()
    masksCreatorCached = self
    print('MasksCreator cached')
finally:
    for f in restore:
        f()

I've patched your extension, and this trick started to work
