Subject: [PATCH] Remove unused headers from gsl/pointers (#1153)

* Remove unused headers from gsl/pointers

forward is already declared in utility, no need to include algorithm which is relativaly heavy
hash is already declared in memory, no need to bring brand-new header system_error for hash only

* Fix: add missing header <functional> to gsl/pointers due to using less/greater
