Allow subsetting TOL classifier

Adds functions to TreeOfLifeClassifier to allow subsetting
the embeddings. The get_label_data() method returns a dataframe
of the labels for the TOL txt embeddings. The create_taxa_filter()
method creates a filter (boolean array) for the txt embeddings
based on a taxa and values. The apply_filter() method filters the
classifier for a filter. The filter is a boolean array with the
same length as the txt embeddings.
