This commit produces the same savings as the compiler options -fshort-enums. Except by setting the types manually we save also 2 bytes of SRAM. By default, the enum type is 2 bytes, with we can explictly set it to one byte when applicable to reduce code size. Almost all the savings from from 'enum Mode' in leds.h. Change in memory: Flash: -116 bytes SRAM: -2 bytes
