[subset] Avoid incorrectly dropping cmap for NotoColorEmoji.ttf NotoColorEmoji.ttf uses two cmap subtables Format 14 | Platform ID 0 | Platform Encoding ID 5 Format 12 | Platform ID 3 | Platform Encoding ID 10 This combination results in the cmap table being dropped during subsetting despite being valid/required.
