I want to merge all working branches with keeping the history of all commits.

Bug fixes.

Fixed a bug in projmat (wannier90). This bug affects only if spin_orbit = True and the orbitals (Wannier basis) are not degenerate.

Improvements

Add dcore_mpicheck. A debugging program that simply launches mpirun.
Moved from Travis CI to Github Actions.
- Removed old Dockerfiles
- Added Dockerfile for VS code, etc.
- Added development information to README (how to run unit tests, etc.)
Refactoring of self-energy symmetrization code (time_reversal now works even if spin_orbit=True)
Improved setup.py
- Avoid using h5py 2.10.0, which contains a bug
- Add dcorelib, toml as dependencies (dcorelib is not used by default)
Improve self-energy analytic continuation
- Export of npz files
- Add dcore_pade
- Code for computing Hartree-Fock term is now involed in src/dcore/dc.py.
All TRIQS library imports are now done via src/dcore/dispatcher.py.
Added option to perform PH symmetrization of the bath energy in the bath fitting of the pomerol solver.
