 * Interface to a MusicXML-to-MIDI converter.
 *
 * The converter is given a MusicXML file and is expected to produce 2 artefacts from it:
 * - A standard MIDI file expressed as an ArrayBuffer,
 * - A "timemap" which is an array of MeasureTimemapEntry structures associating
 *   the index of each measure in the MusicXML file (0-based) to a millisecond offset starting at 0ms.
 *   Repeats and jumps should be explicitly "unrolled" in this timemap
 *   in order for the sheet display to properly sync with the MIDI playback.
 *
 * Refer to the various implementations of this interface for details.
