We currently support epi_week() via the us_week kernel. Can we support epi_year() too?

epiyear in lubridate:
https://github.com/tidyverse/lubridate/blob/10731d1876f8cb902f01f8edb2810a09ce5784a4/R/accessors-year.r#L48-L69

I think this might be somewhat similar to MySQL's yearweek. It doesn't seem to be implemented universally, e.g. I don't think it's a thing in Postgres

If this isn't something desirable to implement at the C++ level, it's still possible to implement at the R level after a number of other temporal-related functions are implemented.
