Separate out a MECE race/ethnicity chart

This would also clear up some potentially confusing results like this (California state level, 1% flat tax, excludes adults (i.e. child allowance)). So White Non-Hispanic, Black Non-Hispanic, Hispanic, Other Non-Hispanic. Presumably the Other Non Hispanic group has a higher poverty impact than the others, bringing the overall poverty impact to 9.2%.
