v0.7.2

• added GCT score to BeadArray controls report, ReportDF
• ReportPDF changes
  • uses noob_meth/unmeth instead of raw, uncorrected meth/unmeth values for GCT and U vs M plot
  • inverted poobah table to report percent passing (instead of failing) probes per sample, like BeadArray report
  • this changed input from 'poobah_max_percent' (default 5%) to 'poobah_min_percent', (default 80%)
  • M_vs_U not included by default, because redundant with qc_signal_intensity
  • M_vs_U compare=True now labels each sample and has legend, so you can see effect of NOOB+dye correction on batch
  • added poobah color-coding to MDS plot
• get_sex improved plotting
  • will read poobah data and size sample points according to percent of failed probes
  • save plots, or return fig, and more options now
  • fixed circleci so it runs unit tests 2X faster
