CPI inflator when dates are nice
cpi_inflator_quarters(from_nominal_price, from_qtr, to_qtr,
adjustment = c("seasonal", "trimmed", "none"),
useABSConnection = FALSE)(numeric) the nominal prices to be converted to a real price
(date in quarters) the dates contemporaneous to the prices in from_nominal_price. Must be of the form "YYYY-Qq" e.g. "1066-Q2". Q1 = Mar, Q2 = Jun, Q3 = Sep, Q4 = Dec.
(date in quarters) the date to be inflated to, where nominal price = real price. Must be of the form "YYYY-Qq" e.g. "1066-Q2".
Should there be an adjustment made to the index? Adjustments include 'none' (no adjustment), 'seasonal', or 'trimmed' [referring to trimmed mean]. By default, seasonal.
Should the function connect with ABS.Stat via an SDMX connection? By default set to FALSE in which case a pre-prepared index table is used. This is much faster and more reliable (in terms of errors), though of course relies on the package maintainer to keep the tables up-to-date.

If using useABSConnection = TRUE, ensure you have rsdmx (>= 0.5-10) up-to-date.
