fix: Address slicing for pyarrow array in data_color

[FBruzzesi]

Summary

Follow up from the disclaimer section in #736

summary

> For pyarrow backed tbl_data, `data_color` the code would end up breaking a few lines down the line when performing the follow operation:

column_vals = data_table[col][row_pos].to_list()

In fact, slicing with a list on a chunked array raises

*** TypeError: 'list' object cannot be interpreted as an integer

I wanted this PR to be atomic enough to solve one issue. I can follow up on this other one

I manually checked a few vs pandas/polars, but more eyes the better

I think it was intended to use index location in the first place but the issue never arise?
