obpg_fetch(
  x,
  nav,
  outpath = NA,
  overwrite = TRUE,
  fmt = "GTiff",
  try_nrt = TRUE
)

`x`	ncdf4 object or URL. If an ncdf4 object, then it will be left open so be sure to close it when you are done.
`nav`	list as returned by `obpg_nc_nav`
`outpath`	character or NA to prevent file writing. If provided, the actually path written to will be <path>/YYYY/mmdd/filename
`overwrite`	logical, see `raster`
`fmt`	character either 'raster' or 'GTiff' (default)
`try_nrt`	logical, if TRUE and the connection fails, then try again after modifying the url to ".NRT.nc" instead of ".nc"
