feat: add SteelSeries Rival 300 family protocol - #219
Conversation
Rival 300 (1038:1710) and its editions (Dota 2 1038:1392, CS:GO Fade 1038:1394, Fallout 4 1038:1712, Acer Predator 1038:1714, CS:GO Fade stm32 1038:1716, HP OMEN 1038:1718, CS:GO Hyper Beast 1038:171A, Evil Geniuses 1038:171C), reconstructed from the vendor's own GG 121.0.0 rival_base.lisp profile with rivalcfg's rival300.py corroborating every byte. Linear DPI 0x03 (50-6500 in 50 steps), polling 0x04, two-zone LED 0x08/0x07, six remappable buttons 0x31, save 0x09, firmware 0x10. Unverified on hardware.

Addresses CodeRabbit: readStatus now reports the active preset's DPI and setDpi writes the active preset (read via 0x16) rather than always preset 1, so a change takes effect after the CPI button switches presets. Both presets are now tracked independently (each falling back to its rivalcfg default), fixing the setDpi/setDpiPreset2 asymmetry. setDpiPreset2 still writes preset 2 explicitly. Adds steelseriesRival300DecodeActivePreset.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Reject an unknown active preset before writing DPI.
If the preset query times out or returns an invalid value while preset 2 is active, readActivePreset selects preset 1. setDpi then writes and saves preset 1, returns success, and leaves the active DPI unchanged. Propagate the query failure to setDpi instead of selecting a preset that the device did not report.
Based on learnings: “avoid silently swallowing errors, falling back to defaults … for unsupported or unexpected states.”
