Reduce max_consecutive_blank_lines to 1
Summary: hackfmt has allowed two blank lines in a row ever since its original prototype. This might be because eshrews-zz figured multiple blank lines were occasionally useful for grouping methods, or maybe he borrowed the behavior from dartfmt. Whatever the reason, we've had requests that we reduce this limit down to 1, so do so.
