Add Broadcom-style postprocessing for APDS9151 color readings in SRSHub

[raahilparikh]

Motivation

• The APDS9151 I2C device exposed by SRSHub provided raw color channel integers that need the same postprocessing/normalization RevColorSensorV3 performs so higher-level code can use RGB/alpha values consistently.

Description

• Added raw color fields (rawInfrared, rawRed, rawGreen, rawBlue) and postprocessed outputs (red, green, blue, alpha, infrared) to SRSHub.APDS9151 in TeamCode/src/main/java/org/firstinspires/ftc/teamcode/util/SRSHub.java.
• Implemented postProcessColors() which subtracts infrared from each channel, clamps negatives, finds the max channel, scales channels to a 0–255 range (Broadcom-style normalization), and computes alpha and scaled infrared.
• Updated parseUpdate() to store raw values from the incoming BitSet into the new raw fields and call the postprocessing step after reading the raw channels.

Testing

• No automated tests were executed as part of this change.
