Pre-Holiday Release

This release has a few bug-fixes and notably new renderers targeting financial applications.

Special thanks to @raven2cz and @HanSolo who contributed to this release. 👍

new features:

• CandleStickRenderer, HighLowRenderer, Basic Financial API (#316, #326)
  For details, please have a look at the snapshots and demos provided.
• GitHub action that runs the tests on each push also for users outside the organisation

bug fixes:

• Correct automatic module names (N.B. may not contain '-' since JDK9 #321)
• Fixed MultiArray and DoubleGrid DataSets to use row-major storage as documented (#329)
  This is an internal change and most users should not be affected by this.
  N.B. rationale: depending on the math sub-domain:
  • algebra (matrices, tensors, etc.) commonly use row-major notation, while
  • charting typically requires column-major order. ie. abscissa (e.g. 'x'-coordinate)==column before ordinate (e.g. 'y'-coordinate) ==row.
    Transposing the dimensions/shape is now done in the top-most DataSet interface that is being plotted.

Finally, a quick show-case of one of the many new financial chart related features:
