fmap: 2.0.0

Updates include several breaking changes as well as improvements to fmap's functions and info. The breaking changes include the removal of the fcircles_plot and fcircles_multi functions from fmap. Other breaking changes involve the renaming of the column containing aggregated counts per polygonal zone (i.e. from 'circle_count' to 'count') in fmap_plot, fmap_data and fmap_multi. Additional updates include changes to fmap's function info and slight improvements to how datasets are generated in fmap
