Fix microstrain rqt quickview after microstrain driver V3

[snwu1996]

After microstrain driver V4 it appears that the rqt quickview is broken.

Running the command

roslaunch microstrain_inertial_rqt quickview.launch driver_namespace:=/sensors/gps

Produces the following error.

process[microstrain_inertial_quickview-1]: started with pid [406991]

[snwu1996]

This branch is currently usable. 80% of the data updates properly and the quickview launches without crashing.

The other 20% I haven't got around to fixing because some of the topic formats changed so fixing it might take a bit more time.

[snwu1996]

I no longer have access to a gq7 to test with so for now this is probably as good as this PR is going to get. This PR is ready for review given the caveat that ~20% of the widgets don't update properly at the moment.
