Error with small sample size

[CarloOtano]

ValueError: n_samples=10 should be >= n_clusters=12.

get_hotspots(...):
    ...
    z = model.fit(vecs)  # Error here!

Notes:

• HDBSCAN not available; using sklearn KMeans
• CUML not available; using umap-learn UMAP

To do:

• [x] Added two more butterflies to test case and issue no longer happens.
• [ ] Need to add error handling.
