"Measureless" files with identically named implicit measures crash the MusicXML parser #142

A file is without measures if all of its timewise measures are set to implicit. A file without time signatures is without beats. Under these conditions, measureEnd and measureStarts, as well as isOnBeat() are irrelevant. MFP.js picks up on this and sends a signal to MFP.vue to deactivate the granularity picker, as well as to OSMD to hide the time signatures (because OSMD adds a 4/4 time signature by default). This has been tested to work with Satie's Gnossienne n°1, with the exception of its identically-numbered implicit measures being renumbered to distinct identifiers (a bug related to musicxml-interfaces, see #142).

This is due to an underlying bug in musicxml-interfaces, see : jocelyn-stericker/musicxml-interfaces#20
Since the repo for this lib appears to be dead, and in lieu of a time-consuming fork fixing this bug, a middleman function could perhaps be introduced as a patch, which would rename identically-numbered measures, although they do seem to be well-supported by Musescore as well as OSMD, so it definitely looks like a fault on the part of musicxml-interfaces itself.
