Since the introduction of the Pixel 9 devices shipping with the AIDL Audio HAL, the number of DynamicsProcessing.EqBand bands is limited to 32 only. This must be a bug as the lead of the DynamicsProcessing project announced that 'you can have as many bands as you wish': https://youtu.be/_hPlNoF1Tyc&t=1179

This issue is crippling many equalizer applications that relied on the freedom of using more than 32 EQ bands and destroys one of the core principles of this library.

Steps to reproduce:

• Compile and open the sample
• Press the FAB to play music
• In the Dynamics Processing fragment, enable 'DPE enable'
• Set the Pre EQ Bandcount to something higher than 32
• Set Pre EQ enable to 'enabled'
• Notice adb logcat containing logs like:

AidlConversionDp: clampParameter from "DynamicsProcessing{preEqBand: [EqBandConfig{channel: 0, band: 32, enable: true, cutoffFrequencyHz: 691.587036, gainDb: 0.000000}]}" to "DynamicsProcessing{preEqBand: [EqBandConfig{channel: 0, band: 31, enable: true, cutoffFrequencyHz: 16222.616211, gainDb: -5.000000}]}"

The log indicates that the EqBandConfig the amount of bands is capped at 31. Any band above band[31] is set to the last band in the EqBandConfig. This is an error both in the sense that it makes apps incompatible with the non AIDL audio HAL and that it leads to different results than the developer specifies.
