Description

when installing this package from a wheel, doing import stsci.tools fails. However, importing tools succeeds.

Expected behavior

❯ python -c "import stsci.tools"

Actual behavior

❯ pip install stsci.tools
❯ python -c "import stsci.tools"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'stsci.tools'

2. install stsci.tools from a wheel (build one with python -m build . or install from PyPI pip install stsci.tools)
3. move to a directory away from the source code
4. attempt to import stsci.tools:

python -c "import stsci.tools"
