some new SRS-Relative (plan to submit)

[jwaldmann]

I plan to submit some SRS-Relative

https://git.imn.htwk-leipzig.de/waldmann/pure-matchbox/-/tree/master/data/srs-relative/waldmann-25

These appear to be hard for matchbox.

Perhaps needs some clean-up first. Currently, file names are random, format is SRS (not ARI).
