Add file with alternative playback data from FR24

For some reason FR24 has two sets of data. This is a script to extract the data upto 17:00 UTC. Need to add some times after this.

There is one additional feeder - T-WMSA8 - that we haven't previously seen.
Lon/Lat have low precision.
Vertical velocity appears to be correct (64 is a factor of all values)
