faer intagration for 2D matmul

[JErnestoMtz]

The current performance of matrix multiplication leaves a lot to be desired, one good first step is to integrate faer. This will help tremendously for Rank 1 or 2 float arrays.

Aany performance improvements in the rapl library have to ensure they seamless integration with the UI. The primary appeal of rapl lies in its exceptional generality and user-friendly nature, so any modifications must preserve and enhance these qualities, rather than detracting from them.
