stop LAPACK least_squares from printing / verbose

[azmyrajab]

Hello!

When running ndarray-linalg least squares (which should use LAPACK SGELSD)
let solution = x.least_squares(&y).map_err(|_| LeastSquaresError::SolveError)?;

I get the following printed out -
start of SGELSD
start of SGELSD
overdetermined, path 1
overdetermined, path 1a
end of SGELSD

Repeated calling of the least squares routine results in flooding sysout and meaningful performance implications (for an otherwise fast implementation).

Is there any way to disable this? or make being verbose optional?

Thanks!
