ENH: Changes (and tests) to allow exporting half-floats through the buffer interface. (#1789)
Code:
Added NPY_HALF to switch (descr->type_num) in _buffer_format_string.
Added 'e' keys to the _pep3118_native_map and _pep3118_standard_map.
Tests:
Added entries to the generic round-trip tests.
Added specialized half-float test that round-trips example values from the wikipedia page.
