Release v1.2 wishlist

[nakib]

• Marti's gigantic nanostructures merge.
• (Revert to) low RAM version of gpu offload. Caching before disk dump requires too much RAM.
• Fix load balance issue in DOS calculator, and perhaps in other places as well.
• Use official fortran api from spglib
• On-the-fly W
• On-the-fly Y
• On-the-fly X
• Hashtable for storing periodic table and isotope data structure for all isotope related data/calculation
• Add more examples (perhaps in the form of tutorials).
  • 4-phonon scattering
  • superconda
  • exciting interface
  • nanostructures
  • phonon-substitution defect scattering
• Add more tests.
• FPMized blas and lapack options.
• FPMized spglib option.
• Ship dependencies in third party directory to allow building on machines without internet access.
• Beyond Tamura ph-iso scattering. Set the better theory as default.
• Improved documentation.
• "Read the org" style website.
• Add openblas option in fpm.toml. Thanks, Sebastian!
• Update to fpm v0.8.
• update to EPW v>=5.9s
• add new wannier parsers (with support for EPW's use_ws flag)
• Reproducible build with gnu guix (maybe...)
• Remove cmake support because life is too short (maybe...)
• Some porting of post processing steps to julia (maybe...)
