feat: add SteelSeries Sensei [RAW] protocol family - #220
Conversation
Sensei [RAW] (1038:1369) and its Diablo III / Guild Wars 2 / Black Ops II / World of Tanks / Heroes of the Storm editions, reconstructed from the vendor's own GG 121.0.0 sensei-raw_base.lisp profile with rivalcfg's sensei_raw.py corroborating every byte. Linear two-preset DPI 0x03 (90-5670), polling 0x04, single-LED brightness 0x05 and effect 0x07, eight 3-byte button slots 0x31, save 0x09, firmware 0x10. setDpi writes the active preset (read via 0x16). Unverified on hardware.

Do not write preset 1 when the active preset is unknown.
readActivePreset returns 1 on a timeout or on an unexpected byte. In that case setDpi writes 03 01 and saves it. It then records the value as preset 1. If the mouse is on preset 2, the cursor DPI does not change. The method still returns dpi as a success. This breaks the documented guarantee that "a change always takes effect". The call also overwrites the stored preset 1 without the user's request. Make readActivePreset return null when the reply fails or contains a value other than 1 or 2. Then make setDpi throw an error, or report the write as unverified, instead of writing to an assumed preset.

Do not disable unmapped buttons on a partial mapping.
setButtonsMapping accepts Partial<...>. The encoder sets every omitted slot to 0x00, which is "disabled". The 24-byte packet replaces all eight slots. A call such as setButtonsMapping({ button8: ... }) therefore disables the left and right click buttons and saves that state to flash. The device cannot report the current mapping. The coding guideline says to "Refuse the write if unknown or reserved state cannot be preserved safely." Require all eight buttons in the mapping, or reject a mapping that omits a button.
As per coding guidelines: "When a write replaces a multi-value setting and the device exposes its current state, preserve unrelated readable values. Refuse the write if unknown or reserved state cannot be preserved safely."

Correlate input reports with the pending query.
onInputReport forwards every input report to the pending waiter. awaitResponse resolves from the first report after sending the query. A report with a different report ID or an invalid payload can therefore consume the waiter before the intended reply arrives. probeFirmware can display firmware from unrelated bytes, and readActivePreset can select preset 1 from an unrelated payload. setDpi can then write and save the wrong preset.
Keep the existing timeout fallback, but leave the waiter pending until the expected report ID and query-specific payload format match.

Update `awaitResponse` to accept a query-specific payload validator and keep its
waiter pending when a report fails validation; resolve with null on timeout as
before. Ensure `onInputReport` only forwards the expected report ID, and have
`probeFirmware` and `readActivePreset` supply validators matching their response
formats.
