//! Suzuki protocol decoder/encoder
//!
//! Ported from protopirate's suzuki.c
//! Aligned with ProtoPirate reference: `REFERENCES/ProtoPirate/protocols/suzuki.c`.
//! Decode/encode logic (preamble count 350, gap 2000µs, short=0/long=1, field layout) matches reference.
//!
//! Protocol characteristics:
//! - PWM encoding: 250/500µs timing
//! - 64 bits total
//! - 350 preamble pairs
//! - 2000µs gap between transmissions
//! - PWM encoding: 250µs HIGH = 0, 500µs HIGH = 1; LOW 250µs after each bit
//! - 64 bits total; preamble: 300+ short LOW pulses then long HIGH starts data
//! - 350 preamble pairs (SHORT HIGH / SHORT LOW); 2000µs gap at end
//! - Field layout: serial = (data_high&0xFFF)<<16 | data_low>>16; btn = (data_low>>12)&0xF; cnt = (data_high<<4)>>16
