raymondEhlers/reactionPlaneFit: Reaction Plane Fit 1.0.1

Note: 1.0.1 resolves a tagging problem related to a rebase. The 1.0 change log is below:

• Zenodo DOI information.
• Chi2/ndf calculation.
• Plot module (with tests) to draw the fit and the residual.
  • The tests take advantage of image comparion.

• Additional fit quality checks.

  ### Fixed

• Parameter argument ordering in the signal inclusive fit. See ba4e833a.

• Fixed error propagation by calculating the error for each individual component rather than for the simultaneous fit (which was the wrong approach). This has the side effect of substantially speeding up the error calculation.
• Specify all initial parameters, limits, and steps, which can substantially improve the chi2.
• Various type annotations.
