cartreader/Cart_Reader/OSCR.h
Ancyker e61ac414d8 Code optimization, cleanup, and stylization 
* Reduced PROGMEM / DRAM usage slightly (Using defaults w/HW5: Before -> 214,668 bytes / 5,757 bytes; After -> 213,414 bytes / 5,751 bytes)
  * Optimized some menu options and calls
  * Added more string constants and implemented them where found.
* Fixed some stylization
  * Constants should always be uppercase.
  * Features should use the `ENABLE_<feature name>` format.
  * Options for features should use the `OPTION_<feature name>_<option name>` format.
  * Added ENUMs for more clarity and better type checking.
  * Moved some defines over to `constexpr` and `const` types. These are preferred over preprocessor constants when not intended for use with `#if` and other preprocessor language.
