Request: Ability for --output-msr-to-stn flag to output the m2s file ordered by Connectivity count

[tekwen]

For our parcel fabric boundary networks, we'd like to start making greater use of the m2s file to help us identify connectivity problems and present these to our users. The file is currently ordered by Station name. It'd be helpful to have the ability to also order the file by increasing connectivity, so that the low connectivity stations are seen first at the top of the file. Ordering by total count would be great, but it'd also be useful to see this ordering by a specific measurement type.

Another approach is a filtering mechanism, where only those stations that have less than a specific total measurement count are reported. The file would be filtered to have only those stations with less than X measurements.
