More packing functions renaming
This MR finishes the renaming of packing functions in the python code which was started by !2227 (merged).
The functions pack
, pack2
, unpack
and unpack2
have now been completely renamed to pack_density
, pack_hermitian
, unpack_hermitian
and unpack_hermitian
, respectively.
There's still the issue of whether we should address the renaming in the C-code as well, but if not, we can then close #963 (closed).
