Subject: [PATCH] fix: add missing space between digit groups in
 comma-separated numbers (#291)

Numbers like 0,013,225 were normalized to "oh zero one threetwo two
five" with "three" and "two" concatenated. The comma-separated digit
groups in single_digits_graph_with_commas lacked a space separator
between groups.
