Handling ODF data with missing units

[JessyBarrette]

Issue

Some of the historical data from BIO is missing units associated with some variables. Exce[t for some specific test files (eg. CTD_BCD2013667_001_01_DN.ODF), only a few variables are more commonly missing units :

• PSAR: Subsurface PAR, more common units are ueinsteins/s/m^2
• SPAR: Surface PAR, more common units are 'ueinsteins/s/m^2`
• FLOR_01: potentially fluorescence or other optical sensors, GF3 term is related to mg/m^3
• FLOR_02: potentially fluorescence or other optical sensors
• FLOR_03: potentially fluorescence or other optical sensors

Potential Method for handling issue

Add those specific terms to the Vocabulary CSV file within the BIO vocabulary and for each variable terms, add to the expected_units column the following: "variable_default_units|None"

This will assume that if ODF conversion includes BIO data, the default value units for the PSAR variables are the "variable_default_units".
