API for pre-allocated calculation for better performance #168

Depends to #167, from https://github.com/rust-ndarray/ndarray/issues/649#issuecomment-504754950

Current implementations of QR and other methods adopt "luxury" way for memory allocation, i.e. qr allocates working memory on every call. This overhead is negligible in some cases where this crate should focus.
