Resolve "Reverb structure memory non-optimality"

• Related issues: #2059
• Requested reviewers:

Reason why this change is needed

• BASOP version used Word16 values for coloration and correlation parameters for reverb, which were eventually converted to Word32. This required redundant memory usage.

Description of the change

• Parameters were stored in tables in Word32 format, and are eventually used directly from ROM.

Affected operating points

• Binaural output with synthetic reverberation.

Closes #2059
