From an indicator for treatment, retrieve start year.
Description
This function returns the earliest year where an indicator == 1.
If indicator never equals zero, return Inf.
This is most useful with
mutate(.by = unit, g = get_min_year(year, treat)) or
DT(j = g := get_min_year(year, treat), by = unit)
to convert between d and g variable in panel data.
Usage

Arguments
