Move all arrays to allocating actual data rather than pointers to simplify construction and destruction. Also moved to M_EACH for iterating over arrays for less boilerplate code.
Also did some function renaming for extra clarity.
root_area is now a node type for simplified area traversal (coming soon).
The goal is to gradually split out NfcWorkerEventReadFelica into more specific decoders, and have the generic NFC-F info screen display info for tags that don't have a specific decoder, similar to how NFC-A works currently.
