Driver for ERDI 905 nm laser rangefinder modules (LR/LRF-A1/SPD1200/LRF-H/LRF-VB series) over UART.
Supports both published ERDI protocol families: the 8-byte 55 AA command/response protocol (LR1000/1200/1500/2000 E-series, LRF1200A1, LRF3000A1, SPD1200 series) and the free-running 5C data-frame protocol (LRF-H and LRF-VB series). Works with HardwareSerial or SoftwareSerial. Every constant is transcribed from the manufacturer manual; per-model units are respected (the VB series reports millimetres, the H series centimetres).
