-* **interpol_na:** When data for more than one date is downloaded, whether to interpolate `NA` values in rasters using the `raster::approxNA` function. Additional arguments for the `raster::approxNA` function can also be passed into `bm_raster`/`bm_extract` (eg, `method`, `rule`, `f`, `ties`, `z`, `NA_rule`). (Default: `FALSE`).

Skipping existing files can facilitate re-running the function at a later date to download only more recent data.
