R/read_erp.R
    read_erp.Rdread_erp() uses the read_abs() function to download, import,
and tidy the Estimated Residential Population from the ABS. It allows the user
to specify age, sex and states/territories of interest. It returns a tibble
containing five columns: the date, the age range, sex and states that the ERP
corresponds to. This makes joining the ERP to another dataframe easy.

  age_range = 0:100,
  sex = "Persons",
  states = c("Australia", "New South Wales", "Victoria", "Queensland", "South Australia",
    "Western Australia", "Tasmania", "Northern Territory",
    "Australian Capital Territory"),
