Clean up Divesoft Freedome time parsing

So Anton Lundin says that the 32-bit timestamp for the Divesoft Freedom
is indeed a signed offset from Jan 1, 2000.

This does that, but also extracts the whole thing into a helper function
and makes sure that there are no overflows at any point by using
"timestamp_t" in the whole series, and all the operations are "obviously
safe" in their types (ie no "unsigned char gets widened to 'int' and
then we shift it left by 24 bits").
