output a pre-exclusion full dataset in 006_exclusions.Rmd

[mzettersten]

Add a tweak to the exclusion dataset to ALSO export a dataset with all data, pre-trial exclusion, but including information about trial errors. Having that dataset output and stored will make certain robustness analyses more feasible (e.g. choosing different trial-based error exclusion criteria)
