Copyright for lbfgsb source package in Sid

Format: https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/
Upstream-Name: L-BFGS-B
Files-Excluded: x.* ._* OUTPUTS/._* ../._Lbfgsb.3.0 linpack.f blas.f *.pdf
Source: https://users.iems.northwestern.edu/~nocedal/lbfgsb.html
 The upstream source contains prebuilt binaries and various metadata
 files, as well as unused copies of LINPACK and BLAS. These are
 removed. It also contains PDFs, to which it seems unclear whether the
 license is intended to apply. These are therefore also removed.
