Initial support for Divesoft Freedom

This parses the dive profile from Divesoft Freedom log file. Only the
depth profile is currently supported. There is also something wrong as
the log file cannot be given as parameter but must be opened or imported
once Subsurface is running. Note that so far no metadata is parsed.
