Update the build process

[rozyczko]

Bringing EDL up to date with respect to the other projects (especially ERL) requires several steps

• [x] 1. Update package versions and test
• [x] 2. Modify the GH workflow files to use the "standard" structure
• [x] 3. Remove poetry and replace with pip, hatchling
• [ ] 4. Add tox for unit testing
• [x] 5. Add ruff for code quality enforcement
• [x] 6. Modify the source to be ruff-compliant (- [ ] 7. Update CFML distributions on the internal pypi server (or have it use pyCFML from the main location))
• [x] 7. Disable CFML due to Python incompatibility
• [x] 8. Update pdffit2 distributions on the internal pypi server
• [x] 9. Replace easyCore based numpy import with the standard import

Changes have been addressed in branch updated_pipeline

using tox would actually require having any tests in the suite... 🤔
