       Show HN: Micro-RLE <=264-byte compression for UART/MCU logs, zero
       RAM growth
        
       I needed to stuff twice the telemetry through the same 115 kbaud
       line on a Cortex-M0+ that only had 8 kB flash left.  Micro-RLE is
       the smallest drop-in I could come up with: 264 B of Thumb code, 36
       B of state, no malloc, worst-case 14 cycles/byte and still lossless
       for every 8-bit pattern.  On the usual sensor streams (ADC, IMU,
       GPS) it's 33-70 % smaller than raw output and boots in < 600 us, so
       you can fire-and-forget from main() before the PLL even locks.
       Repo is a single .c file and a 3-function API--replace the weak
       emit() hook with your UART / DMA / ring-buffer and you're done.
