Can't be used with the latest `shap` package because of the `slicer` version conflict

Nobody has claimed this yet.

Hello,

FastTreeSHAP package has a pinned version of the `slicer` to `0.0.7` and it blocks an update of the `shap` package to the latest version (which requires `slicer==0.0.8`).

An example of the error:
```
poetry add shap@latest
Using version ^0.46.0 for shap

Updating dependencies
Resolving dependencies... (0.1s)

Because no versions of shap match >0.46.0,<0.47.0
and shap (0.46.0) depends on slicer (0.0.8), shap (>=0.46.0,<0.47.0) requires slicer (0.0.8).
And because fasttreeshap (0.1.6) depends on slicer (0.0.7)
and no versions of fasttreeshap match >0.1.6,<0.2.0, shap (>=0.46.0,<0.47.0) is incompatible with fasttreeshap (>=0.1.6,<0.2.0).

```
Would it be possible to make an update to be able to use FastTreeSHAP with `slicer==0.0.8`?
Slicer release : https://github.com/interpretml/slicer/releases/tag/v0.0.8

Thanks!

Start by locating FastTreeSHAP's dependency declaration and checking how its pinned slicer version is resolved with shap 0.46.0. Confirm the package can install alongside slicer 0.0.8 and that the dependency metadata or relevant installation checks show the conflict is resolved.
