Major changes before Refactoring / Reimagination!file_io/io_vectordata:    ovf-files now can specify the segment that should be read    (if several exist)    vtk-files: fixed an error switching up dim/origin/spacing    major rewrite of _interp_to_regular_grid, now sets up Delauney    triangulation only once (reusable for different magnetisation    components), grid spacing is now mandatory and a conversion factor    is introduced, which can be used to convert units in the vtk file    to nm. Deleted much unused stuff.magcreator/examples:    Added Bloch and Neel type skyrmion support, based on...magcreator/magcreator:    Added create_mag_dist_skyrmion function, which can add Bloch and    Neel type Skyrmions with two different mathematical descriptions    for the domain wall. Fully supports 3D orientation.utils/lorentz:    Added a section to check the phase plate, currently commented out!    Maybe useful in the future or for a full forward model.colors:    Ignored (unavoidable) flake errors (Axes3D "Unused Import")fieldconverter:    Fixed error (wrongly used abs instead of sqrt), now works!    Streamlined convert_A_to_B.fielddata:    field property is now abstract and implemented in subclasses.    angles parameter commented out (delete in the future).    Reenabled axis.set_facecolor(bgcolor) in plot_field (now works!).phasemap:    Made the switch to cmocean.cm.balance colormap (switched colors!)plottools:    Changed figsize default (better fits for newer matplotlib).    New scalebar implementation (black bar now, can have stroke).    Streamlined add_cbar function.    hideaxes now works again (old version used deprecated code)..gitignore:    More general definitions of ignored files.environment.yml:    Updated environmet.

Removed warnings for tight_layout (get rid sooner or later!)
And another environment update (pyFFTW now again accessible via conda!)

dataset: plot_mask now takes kwargs.
fielddata: pad now allows mode changes.
phasemap: fixed bug that did not properly scale vmin and vmax with unit.
io_vectordata: added support for .vtk, .tec files and new interpolation.

environment.yml: upgraded to scipy=1.0

Changed gitlab-ci.yml to use pip install -r requirments.txt instead
(which installes EVERYTHING!)

Added environment.yml and requirement.txt.
GitLab should now produce html coverage artifacts.
io_vectordata: now warns if grid spacing is not equal in all directions.
