Subject: [PATCH] hpx: receiver: Remove std::move() call
This fixes the following warning:
|/home/kurt/git/libgeodecomp/src/libgeodecomp/communication/hpxreceiver.h:138:29: warning: moving a local object in a return statement prevents copy elision [-Wpessimizing-move]
| 138 | return std::move(vec);
The compiler should be smart enough to optimize the correct way :).
