Subject: [PATCH] OpenSpool: parse additional_color_hexes for multicolor spools

OpenSpool tags may carry extra colors in `additional_color_hexes`
(used by the Snapmaker U1 extended firmware for dual/rainbow spools).
The processor previously kept only `color_hex`, dropping the rest.

Append up to 4 additional colors (5 total, matching the U1's
FILAMENT_PROTO_COLOR_NUMS_MAX) to `colors`, using the tag's alpha.
Single-color tags produce the same output and unique_id as before.

Adds a dual-color (red/blue) OpenSpool fixture.
