Flight number sometimes appears in logger serial number

[alistairmgreen]

This bug is seen with LX flight recorders. The header record looks like this: ALXVJF8FLIGHT:1 where:

• A means "This is the flight recorder ID",
• LXV means "Manufactured by LX Navigation",
• JF8 is the logger serial number,
• FLIGHT:1 is a comment.

The serial number of the logger is incorrectly displayed as "JF8FLIGHT:1" (with the comment stuck onto the end).

According to the IGC standard:

• The serial number should be exactly three characters. (LX obeys this.)
• Any additional information after the serial number should be preceded by a comma. (LX does not obey this!)
• The additional information is not required to conform to any particular format.
