Change module import name from pals-schema to pals

[EZoni]

Overview

Keep the distribution name as pals-schema, but change the import name to pals. Close #23.

With these changes:

• Users will install the package with pip install pals-schema.
• Users will import the module with import pals.

To do

• Test with TestPyPI, https://test.pypi.org/project/pals-test/:

  conda activate dev  # activate environment with pip, build, twine, etc.
  cd pals-python  # move to the pals-python root dir to build and upload
  python3 -m build
  python3 -m twine upload --repository testpypi dist/*
  cd .. # move out of the pals-python root dir to install and test the package
  python3 -m pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple pals_test
  python3
  >>> import pals
  >>> from pals.BeamLine import BeamLine
  >>>

• Update the PyPI package version to 0.2.0.
