Create svd_wrapper and copy ginv to avoid LAPACK errors

[GFabien]

Wrap the calls to the svd function in the RGCCA package into the svd_wrapper function to avoid LAPACK errors as done in the JIVE package. SVD are performed in RGCCA in the block initializations (when init = TRUE) and through the calls to the MASS::ginv function. Therefore, this last function has been reimplemented in the package and calls the wrapper instead of the original SVD function.

Aims to solve #82.
