Handling keyboard input in the PET 2001 character device is rather meh, be nice if this could be done in its own plugin for purposes of reuse between different character device implementations

Requirements besides the obvious:

• Should be able to catch key events on an ImGui window of choice
• Adjustable keymap

The changes from #4 cause symbol lookup errors upon loading a second instance of a plugin, due to the new namespace not having access to symbols in the main namespace

This currently causes a load failure on PIA2 with configs/{pet2001,basic4,basic4_turbo}.yaml (though nothing needs it right now anyways)

Currently, plugins that provide an update function run it on each CPU clock cycle, which slows things down tremendously

Perhaps some sort of "run Plugin1 update on clock cycle X" system could be implemented without sacrificing emulation accuracy

(lol as if) (well maybe) (eventually)

blocked on (at least) #2, #3, #6

Plugins should be able to have their own configuration options they can access at runtime

To think about: Maybe these should be shared between all plugins, so that e.g. Plugin1 can look up ConfigOptionA of Plugin2

The reason plugin_callback exists is because I couldn't get plugin-to-program symbol binding (e.g. extern Emu6502 cpu working. This should be re-evaluated, because void* arguments with a cast are an ugly C-ism.

Best-case: plugin-to-main symbol binding can work -> no callback, provide a few useful functions for plugins to use

Worst-case: have plugin_init populate a list of function pointers instead of a single callback
