rraadd88/htsimaging: Single particle tracking to monitor endocytosis in yeast

For single particle tracking to monitor endocytosis in yeast, this release uses YeastSpotter (Lu et al. 2019) for cell segmentation, scikit-image (van der Walt et al. 2014) for image processing, Trackpy (Allan et al. 2019) for single particle tracking and SciPy (Jones et al. 2016) for generating metrics
