Add support for playdate.keyPressed #2
Description
The Playdate Lua and C APIs expose a keyPressed callback/event that was intended to be used for debugging, but maybe Playwrite could support the function as well to implement keyboard support via the Simulator/other tools that send keyboard input to the Playdate?
Thorough testing has revealed that some keys (most notably the letter A and all the uppercase letters) are completely unusable in the Simulator, but that doesn't mean the device doesn't support them. See this gist I made for a complete list of the testable keys in the Simulator.
