Remove false NCLS

Summary

As said in #1921 (closed) the NCLS filter we had was doing nothing more than the UCLS filter. That is why I removed it from the application choice and also from OTB.

Rationale

This filter was doing the same thing as an unconstrained least square. Have a look at the for loop here and replace all the matrix to see that correction=0
