Added setFilterChipProps

[patorjk]

New option that allows you to add props to the Filter Chip component. Works identically to the other setXProps methods. Example:

  setFilterChipProps: (colIndex, colName, data) => {
    //console.log(colIndex, colName, data);
    return {
      color: 'primary',
      variant: 'outlined',
      className: 'testClass123',
    };
  }

Useful for easily customizing to a filter chip. This can already be done through the custom component feature, but doing it that way is a bit of work. Using setFilterChipProps would make customization a lot easier.
