Outdated documentation

[safl]

Items to fix

• [ ] The documentation at https://samsungds.github.io/Spex/setup/manual.html#sec-setup-manual directs the user to look at setup.cfg which no longer exists.
• [ ] The documentation at https://samsungds.github.io/Spex/what_is_spex.html
  • has: a section with no other content than ...
  • has: TODO: Where is the list of things?
  • This should be cleaned up
• [ ] The README.md contains references to the OpenMPDK organization which the project has moved away from
• [ ] The README.md describes use of docker which seems to no longer exist. E.g. make dev-docker-build dev-docker
• [ ] The documentation at https://samsungds.github.io/Spex/setup/nix.html#
  • Specifies that spex can be run with nix run github:SamsungDS/Spex#spex, however, when passing arguments, like one would normally do, then this these are parsed as arguments to nix run not to spex. Thus, this should probably document how to do so, e.g. nix run github:SamsungDS/Spex#spex -- *.docx -s --output docs
