bedrock: fix camera_instruction fade structure (time_data/color_rgb optional prefixes) 1.20.30+

[AnonymoDGH]

Fixes #1109

Root cause: In packet_camera_instruction, the fade instruction was defined without the optional prefixes that each of its fields has on the wire. Per pmmp/BedrockProtocol, CameraFadeInstruction is: Optional<CameraFadeTimeData> (bool + 3×f32) followed by Optional<CameraFadeInstructionColor> (bool + 3×f32 RGB).

minecraft-data had:

fade?:
   fade_in_duration: lf32
   wait_duration: lf32
   fade_out_duration: lf32
   color_rgb: vec3f

which misses the two per-field presence booleans, so any real-world packet using both time and color fails to parse (PartialReadError on all versions from 1.20.30).

Fix (all versions 1.20.30 → latest):

fade?:
   time_data?:
      fade_in_duration: lf32
      wait_duration: lf32
      fade_out_duration: lf32
   color_rgb?:
      red: lf32
      green: lf32
      blue: lf32

Verification: the reporter's 34-byte sample (rAIAAAEBAAAAPwAAwD8AAAA/AeHgYD3BwMA90dBQPgAAAA==, pid 300) previously failed with PartialReadError on every version; with this fix it decodes fully (34/34 bytes) via protodef:

{"name":"camera_instruction","params":{"fade":{"time_data":{"fade_in_duration":0.5,"wait_duration":1.5,"fade_out_duration":0.5},"color_rgb":{"red":0.05490196,"green":0.09411764,"blue":0.20392157}}}}

All affected protocol.json files regenerated via compileProtocol.js.
