spanner 1.0.1

Dependencies for raster now replaced by terra and calls to sp replaced with sf (in spanner only).
Consumed the ransac cylinder fitting code from TreeLS and removed it as a depends/import. This code had to be modified slightly to bring it in line with R for 4.1.2.
Updated get_raster_eigen_treelocs to better handle tree cover when smaller slices are needed.
Updated the readme file to include all relevant literature.
Fixed a bug resulting in treeID's from segment_graph not matching those created in get_raster_eigen_treelocs. Added parameters to specify where the point cloud slice should be used for matching resulting IDs (so they correspond to those provided from get_raster_eigen_treelocs)
