No wheels for releases newer than 0.13

[bartbroere]

Steps to reproduce:

Install the bunq_sdk using micropip in Pyodide for example:

import micropip

await micropip.install('bunq_sdk')

or if you want only binary releases, you could reproduce this with "normal" pip as well:

python3 -m pip install --only-binary bunq_sdk bunq_sdk

What should happen:

The newest version should be installed. In my opinion ideally there should be both a binary and source release on PyPI for each version.

What happens:

A very old version (0.13) gets installed, since that was the last release to include a pure Python wheel.

To fix this

I'm not sure what process uploads the releases to PyPI, but I think it could be worthwhile to build and publish the wheel version as well as the source release, by doing something like this:

python3 setup.py bdist_wheel
python3 -m twine upload dist/*

Extra info:

Relates to this PR: pyodide/pyodide#3801, because I first suspected simplejson caused this. Since I'm (not by choice) installing an old version of the bunq_sdk I got a very old version of simplejson.
