please fix SPDX- tags so they match the actual license. If in doubt about the right tag, check with Mark.

Think I've got the right SPDX in pyproject.toml now: changed it from 'GPL-3.0-only' to 'GPL-3.0-or-later'.

The __license__ in wolfcrypt/__init__.py doesn't seem to be SPDX so I just updated it to GPLv3-or-later.
