docs: Parse masures using a time meter to get a sequence
  
  @param {String} meter - the time meter
  @param {String} measures - the measures string
  @param {Function} builder - (Optional) the function used to build the notes
  @return {Score} the score object
  
  @example
  measures('4/4', 'c d (e f) | g | (a b c) d')
