works faster than fast.date
Examples
exampleDataR = data.table::as.data.table(exampleDataR)
exampleDataR = exampleDataR[,dateformat:= date_mdy_ymd(date)]
#> Error in date_mdy_ymd(date): could not find function "date_mdy_ymd"
faster_date(exampleDataR,"dateformat")
#> Error in data.table::setnames(dt, dateCol_a, "SuperDummyDate"): Items of 'old' not found in column names: [dateformat]. Consider skip_absent=TRUE.
