* Reference combos by index, not 32-bit pointers, and store bitfields instead of arrays in several places, to bring down our flash/RAM usage. * Use bit field to track candidate combos, to avoid needing an explicit `ZMK_COMBO_MAX_COMBOS_PER_KEY` setting. * Determine the max keys per combo automatically from the devicetree, so we remove the ZMK_COMBO_MAX_KEYS_PER_COMBO Kconfig symbol.
