OSD data parsed incorrectly
I have a flight log that is producing gibberish data. I have tested with PhantomHelp, and that is able to parse the data correctly 🤔
Here is some sample output:

@lvauvillier I'll share the flight log with you privately
Missing record types
While processing some M3E flight logs, I found the following record types to be unhandled. I have noted the FlightRecordDataType from the DJI FlightRecordParsingLib repo.
I also noticed that the output I get is missing some key data (e.g. RC, BATTERY, WEATHER), but they are present in the output I get from PhantomHelp.
- 10:
ShowWarningFlightRecordDataType - 17:
VisionGroupDataType - 45:
RTKDifferenceDataType - 48:
AgricultureGroundStationPushData - 55:
npzeXkozKlNHPjUQ - 57:
GOAirLinkDataField - 62:
RemoteControllerDisplayField - 63:
FlightControllerCommonOSDField
I believe 55 might contain battery information, but I haven't had any luck decoding it.
called `Option::unwrap()` on a `None` value
I'm still trying to recursively process that very large dataset... seeing this one now.

EXIF lat / lon fields incorrect?
Looks like the Longitude field is borked?
You can spot check with https://exifinfo.org, or on my Mac this shows up on the file info screen.
Error: failed to fill whole buffer
Same dataset as before... a few files trigger this error. Any idea what may cause it?
