Re: make metronomeMarkFormatter more flexible (issue 327620043 by address@hidden)

Maybe we should think about another subproperty for text like "M. M."
that is placed before the note but after the opening parenthesis if
there is one. This can be neither in the tempo text (\tempo "Allegro M.
M." 4 = 120 would put it before the parenthesis) nor in the parenthesis
text (\tempo 4 = 120 would omit it).
