Description: Make it possible to switch the PicoLCD device between LCD
(firmware) and bootloader (flasher) operation modes.
Reading: returns list of available modes, the active mode being
enclosed in brackets ('[' and ']')
Writing: causes operation mode switch. Permitted values are
the non-active mode names listed when read, optionally followed
by a delay value expressed in ms.
Note: when switching mode the current PicoLCD HID device gets
disconnected and reconnects after above delay (default value
is 5 seconds though this default should not be relied on).
