722462c38b chore: upgrade Lance and rename score to _distance (#398)
BREAKING CHANGE: The `score` column has been renamed to `_distance` to
more accurately describe the semantics (smaller means closer / better).

3c46d7f268 Handle NaN input data (#241)
Sometimes LangChain would insert a single `[np.nan]` as a placeholder if
the embedding function failed. This causes a problem for Lance format
because then the array can't be stored as a FixedSizedListArray.

Instead:
1. By default we remove rows with embedding lengths less than the
maximum length in the batch
2. If `strict=True` kwargs is set to True, then a `ValueError` is raised
if the embeddings aren't all the same length

04d97347d7 move tantivy-py installation to be separate from wheel (#97)
pypi does not allow packages to be uploaded that has a direct reference

for now we'll just ask the user to install tantivy separately
