Tempo control not working

Tempos of music are now always 120 quarter notes / minute. This is due most likely to recent updates in verovio (so either the humdrum converter needs updating or there is a bug in verovio).

Setting MM20 to any value will always result in the equivalent to MM120 being the tempo.
