Feature request: Support for modifier keys to be used in combination with other keyboard keys (example Ctrl+G) for CC command assignments.

Current functionality: Crewchief recognizes all single key presses, including shift, control and alt as actual buttons, not modifiers. So Shift+Y and Shift+L are both logged as Shift only (the first assignment will be deleted of course). Access to F13 to F24 keys are also not recognized, since they are also combo keys (Shift+F1 = F13).

Reason: With the rise of devices like the Elgato Stream Deck being used as simracing button boxes (which are not gamepads; they only send keyboard commands), keyboard functionality should be expanded to Combinations like Shift+Y or Ctrl+Alt+K for example. Assigning CC commands to a single keyboard key is impractical; typing a sentence in a chat for example will invariably trigger a CC command if done this way. Not to mention most single keyboard keys are already assigned to various functions in sims (including F1 to F12). Adding this not only solves these issues but should add at least 5x the possible button assignments when using keyboard.
