emacs.pkgs.mind-wave: remove

- This package cannot be accessed normally because it does not add an
entry to the manual-packages.nix file.  Since there is no issues
raised about this, probably no one uses this package.

- The quality of this package is not on par with other packages.
  - about nix expression:
    - Its passthru.updateScript does not work.
    - It introduces an elisp dependency markdown-mode wrongly.
    - It uses pkgs.
    - It has a redundant parameter substituteAll.
    - It contains a huge block of unneeded comments.
  - about functionality:
    - It does not work out of the box because it does not patch
    mind-wave-python-command.
