J. Nick Koston 0ca44e061e [logger] Move log level lookup tables to PROGMEM 
Move LOG_LEVEL_COLOR_DIGIT and LOG_LEVEL_LETTER_CHARS arrays from
.rodata (RAM) to PROGMEM (flash) on ESP8266. These small lookup
tables were consuming 16 bytes of RAM unnecessarily.

Results on a minimal ESP8266 config:
- RAM: -16 bytes (.rodata 948 → 932 bytes)
- Flash: +32 bytes (PROGMEM access code)
