.asv files should be removed from the repository

[ufechner7]

These files, for example, should be removed:

• https://github.com/TUDelft-DataDrivenControl/FLORIDyn_Matlab/blob/main/FLORIDynCL/FLORIDynCL.asv
• https://github.com/TUDelft-DataDrivenControl/FLORIDyn_Matlab/blob/main/FLORIS/Gaussian/getUadv.asv

.asv files are backup files, no need to keep them in git.
