Fix EDAX binary reader and prepare for 0.8.6 patch release

[hakonanes]

Description of the change

Fixes:

• A bug where patterns from an EDAX binary .up1 file appears shifted horizontally. This was because of an incorrect offset for
  the pattern starts.
• Allow reading of EBSD patterns from H5OINA files without explicit information about the camera binning factor.

Other changes:

• Use numpy.memmap() instead of numpy.fromfile() for non-lazy reading of patterns from EDAX binary up1/up2 files. This should reduce memory use when the pattern array is only read and not written to.
• List OpenECCI and PyEBSDIndex among related projects.
• Add two recent publications using kikuchipy to the list of applications.

Prepare to release these fixes and change as a 0.8.6 patch.

Progress of the PR

• Docstrings for all functions
• Unit tests with pytest for all lines
• Clean code style by running black via pre-commit

For reviewers

• The PR title is short, concise, and will make sense 1 year later.
• New functions are imported in corresponding __init__.py.
• New features, API changes, and deprecations are mentioned in the unreleased
  section in CHANGELOG.rst.
• New contributors are added to release.py, .zenodo.json and
  .all-contributorsrc with the table regenerated.
