feat: add device and emulator screens

Change replaces Options and groups every option by intent. Device chooses --target or --every-board, the board read on the device or named by the card first and chosen. Emulators ticks --emulator. From a pack and Without the internet are rows of their own. Parity tests install the screen's argv and the flag's into two folders and compare dest and sha1.
