check on a few puzzling cases of missing data towards the end of the pipeline

[mzettersten]

These participants get passed through the pipeline despite having no test trial data

• babylabNijmegen_RU_022-toddlers: only calibration data in the eyetracking file by the end of 005
• babylabUmassb_UMB034-adults: only calibration data in the eyetracking file by the end of 005
• babylabNijmegen_RU_021-adults: only familiarization trials
• babylabNijmegen_RU_009-toddlers: only familiarization trials

• socialcogUmiami_UMIA012-adults: seems to be missing from eyetracking data?

[mzettersten]

figured out socialcogUmiami_UMIA012-adults: they are missing age information and something was going wrong in applying the age exclusion, apparently

I checked the raw data files of these participants and found the following (identical to what we have towards the end of the pipeline).

babylabNijmegen_RU_022-toddlers: raw data has no familiarization and test trials; only calibration
babylabUmassb_UMB034-adults: raw data has no familiarization and test trials; only calibration

These two don't get excluded as they don't have any eye tracking data, once we remove calibration trials and have NAs whenever we merge exclusion criteria back into et data. They can however be excluded through the new variable only_calibration_et in combined_demo data frame.

babylabNijmegen_RU_021-adults: raw data has no test trials
babylabNijmegen_RU_009-toddlers: raw data has no test trials; in addition, all trials are marked as lab_reported_trial_errors in the demo

These two get excluded through valid_first_test_trial exclusion.
