+TMTC rev: 15adb9bf2ec68304a4f87b8dd418c1a8353283a3

 ## Fixed
 
 - Bugfix in FSFW where the sequence flags of the PUS packets were set to continuation segment (0b00)
   instead of unsegmented (0b11).
 - Fixed usage of uint instead of int for commanding MTQ. Also fixed the range in which the ACS Ctrl
   commands the MTQ to match the actual commanding range.
+  PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/363
+- Bugfix in FSFW where the MGM RM3100 value Z axis data was parse incorrectly.
