PlantCV v3.7.0

• Dropped Python v2.7 support (https://python3statement.org/).
• Added a Hyperspectral tool sub-package:
  • Read in ENVI hyperspectral data with new option for the existing plantcv.readimage function. While reading in hyperspectral data a pseudo-rgb image is also created.
  • Calibrate raw hyperspectral image data with white and dark reference images with plantcv.hyperspectral.calibrate.
  • Calculate indices (e.g. NDVI) from a hyperspectral datacube with plantcv.hyperspectral.extract_index.
  • Extract bands from a hyperspectral datacube that are the closest to user defined wavelengths with plantcv.hyperspectral.extract_wavelength.
  • Add functionality to the existing function plantcv.apply_mask that allows users to mask hyperspectral images.
  • Add documentation pages and edit existing documentation pages to reflect all additions.
  • Add a hyperspectral workflow tutorial.
• Add documentation
  • Underlying functions used in plantcv-workflow.
  • Information about updating PlantCV.
• Minor update to plantcv.morphology.segment_sort to ensure the function is robust.
• Enhance various region of interest plantcv.roi.* functions to draw the debug image before hitting the fatal error when an ROI extends beyond the image boundaries and start printing a warning if a user defined grid causes ROI's to overlap
