`simdec.tableau` function modifies `states` argument

Raising as part of JOSS review openjournals/joss-reviews/issues/6713

Currently the simdec.tableau function modifies the states list argument passed to the function in the for loop in lines

https://github.com/Simulation-Decomposition/simdec-python/blob/da28df6c981d5ac45f843a4b96fbfd227ed6604f/src/simdec/visualization.py#L228-L234

This results in a cryptic TypeError: slice indices must be integers or None or have an __index__ method error if calling simdec.palette subsequently on the same states argument, for example (running from root of repository)

import numpy as np
import pandas as pd
import simdec as sd

data = pd.read_csv("tests/data/stress.csv")
output_name, *variable_names = list(data.columns)
inputs, output = data[variable_names], data[output_name]
sensitivity_analysis_result = sd.sensitivity_indices(inputs=inputs, output=output)
decomposition_results = sd.decomposition(
    inputs=inputs,
    output=output,
    sensitivity_indices=sensitivity_analysis_result.first_order
)

table, styler = sd.tableau(
    var_names=variable_names,
    statistic=decomposition_results.statistic,
    states=decomposition_results.states,
    bins=decomposition_results.bins,
    palette=sd.palette(decomposition_results.states)
)

sd.palette(decomposition_results.states)
