Bug#929325: libmseed2: New upstream version (requires a transition)

[Paride Legovini]

Package: libmseed2
Version: 2.19.6-1
Severity: normal

Upstream is going to release a new major version of the library: libmseed3.
For the moment the 3.x tags are marked as pre-releases on GitHub.
Once released as stable and once Debian is out of the freeze I'll package the
new version and request the transition. Progress will be tracker here.
