Refactor Build system and CI

[LecrisUT]

• Refactor CMake build system
  • removed cmake-format: that thing just interferes so much
  • Note: this uncovered a bug in CMake FindBLAS and Fedora's openblas packaging
    Basically neither add /usr/include/openblas to the build. Need to recruit some help for this issue.
• Cleanup repo and pyproject.toml
• Update pyproject.toml metadata:
  • classifiers
  • description: Need a better one-line summary of the repo and project
• Cleanup dependencies: some dependencies like matplotlib would benefit from being in optional-dependencies
• Refactor CI:
  • Add cibuildwheel
  • Add RTD builder
  • Run test CIs outside of conda environment
