Research direction

Start by comparing FastTreeSHAP with the latest SHAP behavior for LightGBM data containing categorical values, using SHAP issue #2144 as the reference case. Reproduce the reported failure and determine the scope of keeping FastTreeSHAP in sync; done means the categorical-data case works and the relevant behavior is covered.

Description

Hi, love your package. Will it receive an update so its in sync with SHAP? Preferably it would be nice if we could distill the computation and perhaps propose a PR for SHAP, since keeping up to date with shap might be infeasible.

For example when running Fasttreeshap I found a bug related to Lightgbm where if the data contained categorical values it wouldn't run: https://github.com/shap/shap/issues/2144

This is fixed in the latest shap but not in FastTreeSHAP.
