[DJI-log-discuss] Header scrambled in latest log files

Anybody got any insight into what has happened with the TXT files produced
by the DJI software recently?  All the zeroes (0x00) have disappeared from
the 100 byte header and seemingly have been replaced with (0x20) although
visually the structure looks similar.

However, xor-ing the header bytes with 0x20 doesn't retrieve anything
useful, the recordsAreaEnd bytes aren't big enough in the sample I have and
the detailsAreaSize number doesn't look right either.  The weirdest part is
that the numbers where you would expect recordsAreaEnd (i.e. the first 4
bytes) don't have any numbers in byte 3 and 4 which leads me to think they
have changed the meaning of that number somehow.  This is my first time
digging around with the TXT files so I could be way off.
