Update hexcode 48D852 (and hexcode 48D84D)

[rdjsb]

Albert,

Casa 295 with serial 023 flew friday 10/04/2015 with hexcode 48D852 to and from Leeuwarden. In your database this hexcode has no serial.
Serial 023 is in your database as hexcode 48D84D, but that's maybe not right given the above.

Regards,
Roland

THanks for the update!
