 Currently, libdivecomputer only parses the tank pressure stored in the
 sample data, but not the dive header. The consequence is that the tank
 pressure is only reported for those devices that record a complete tank
 pressure profile. For those devices that store only a single tank pressure
 value in the dive header, the dc_parser_get_field interface should be
 extended with tank pressure support.
