Vignette documents use of all functions in workflow to update vascular plant indicators (for NI2025)
All functions now use relative paths
All data is now saved as .rds instead of .RData (solves #3)
Updated GBIF download query to only download data for relevant species (instead of all plants)
Filtering for making species-specific training data sets has been updated. Now avoids dropping relevant occurrences, but uses only presence records (no absence records)
