amadeus: Improve and fix delay effect processing (#3205)
* amadeus: Improve and fix delay effect processing

This rework the delay effect processing by representing calculation with the appropriate matrix and by unrolling some loop in the code.
This allows better optimization by the JIT while making it more readeable.

Also fix a bug in the Surround code path found while looking back at my notes.

* Remove useless GetHashCode

* Address gdkchan's comments
