FloatArray Log Messages

[stephanbro]

• Use Float32MultiArray instead of GenericLogMessage to allow easier plotting (in rqt_plot for example)

Depends on bitcraze/lps-ros#7

Those changes look good to me. I will need to wait for the other two dependent changes in order to merge it though (I added a comment/question in the firmware pull request regarding that change).
Thanks!

The PR bitcraze/lps-ros#7 is dependent of this. As far as I can tell it is the last dependency for this PR. As soon as this PR is merged I will be able to merge bitcraze/lps-ros#7

That switch loses the time information of the header. Without the time, it will be difficult to plot data correctly (the main feature of the timestamp is that you can select the on-board timestamp, allowing to get clean plots over time for the various logging variables).
Would it help to change https://github.com/whoenig/crazyflie_ros/blob/master/crazyflie_driver/msg/GenericLogData.msg#L2 to Float32MultiArray instead for plotting?

Ah that's a good point. I don't have time to work on this these days, so I'll close this PR until I get a chance to look at this again.
