New cleaned R27 table (SENSOR_MODEL): DAC Implementation steps

[cgourcuf]

Once #112 has been done:

• For new floats, DACs should use the cleaned NVS version of R27 to fill SENSOR_MODEL in coordination with the uncontrolled SENSOR_FIRMWARE_VERSION

• As time permits, DACs are asked to go back and update SENSOR_MODEL to new constrained R27 vocabulary with addition of SENSOR_FIRMWARE_VERSION using mapping from Google sheet on ADMT website for reference.

• At ADMT-26, check with DACs to see if they are ready for GDAC File Checker to move to cleaned R27 version. (Action for co-chairs)

• GDAC File Checker: continue using the google sheet (downloaded & served from ADMT website) of SENSOR_MODEL entries based on the old R27 so DACs can continue to submit Argo meta files (Thierry).
