Non-geographic partner function to geo_estimate_up. Allows users to aggregate up without the costly matching operation if they've already matched.
estimate_up(value, group)numeric vector. Defaults to 1. Typically population values.
matches of length(value) that correspond to row indices of value. Often, this input is the output of geo_match.
numeric vector with each value aggregated by group
