import setuptools for successful pip install

[spmeisburger]

Install using conda and pip didn't work for me -- it failed to install the sub-package bioxtasraw.denss_resources. To fix it, I modified setup.py to use setuptools.find_packages. The goal here is to enable a one-line linux install like this:

micromamba create -f raw_env.yaml

With raw_env.yaml as follows:

name: raw-2-2-2
channels:
  - conda-forge
dependencies:
  - python >=3.9,<3.10
  - numpy
  - scipy
  - matplotlib
  - pillow
  - numba
  - h5py
  - cython
  - reportlab
  - wxpython
  - dbus-python
  - fabio
  - pyfai
  - hdf5plugin
  - mmcif_pdbx
  - svglib
  - pip:
    - git+https://github.com/jbhopkins/bioxtasraw.git@v2.2.2
