This release includes substantial changes to data processing
functions in order to process data from SBE43 dissolved oxygen
and SBE18 pH sensors.
NEW FEATURES
Modifications were made to numerous core functions to handle
data from dissolved oxygen and pH channels while retaining
functionality when the sensors are not used.
derive_oxygen(): Converts SBE43 voltage into oxygen (ml/l)
using calibration parameters for the DO sensors. Currently
allows tau correction to voltage but not the hysteresis correct-
ion. References:

extract_calibration_xmlcon(): Extracts calibration parameters
for temperature, pressure, conductivity, dissolved oxygen, and
pH sensors from a CTD configuration (.xmlcon) file.
align_oxygen(): Aligns oxygen channel data using user-specified
offset value.
wrapper_align_oxygen(): Aligns oxygen for multiple user-specified
alignment offset values using align_oxygen().
select_best_oxygen_method(): Similar to select_best_method()
for temperature/salinity/density, an interface for users to
select the best oxygen alignment value based on visual inspection
of oxygen profiles.
review_oxygen_ph_profiles(): Similar to review_profiles() for
temperature/salinity/density, an interface for users to select
oxygen and pH profiles to include in the final data product.
FUNCTIONALITY CHANGES
qc_flag_interpolate(): Allows "oxygen" and "ph" as arguments
to 'review'
.check_duplicates: Internal (AFSC) use. Checks hex files for
duplicate casts and multiple serial numbers to avoid processing
errors.
