This commit adds a new template hook exploreSketch() that allows plugins to efficiently obtain compile-time known information about the sketch. The hook is called before setup and is passed a _Sketch template parameter that wraps two more types Plugins and StaticKeymap, whose static constexpr methods can be used to explore the registered plugins and the static keymap.

// that is declared 'constexpr PROGMEM' must either be accessed

// access at run-time will cause a memory access failures as the MCU

// There are some functions that are therefore restricted to compile-time
