fetch_all(origins = all_possible_origins, write_to = NULL,
  sleep_time = 1, n_tries = 3, as_range = FALSE,
  show_details = FALSE, verbose = TRUE)

`origins`	A vector of origin zips. Defaults to all possible origin zips from 000 to 999.
`write_to`	The path to a CSV file to create and append each result to.
`sleep_time`	How long to sleep in between requests, plus or minus `runif(1)` second.
`n_tries`	How many times to try getting an origin if we're unsuccessful the first time?
`as_range`	Do you want zones corresponding to a range of destination zips or a full listing of them?
`show_details`	Should columns with more details be retained?
`verbose`	Message what's going on?

For all the 3-digit origin zip codes, grab all destination zips and their corresponding zones. This is equivalent to running fetch_zones_three_digit for all possible 3 digit origin zips.

If this fails partway through, origins that could not be retrieved get a "no_success" value in their dest_zip and zone columns but we continue trying to grab results for all supplied origins.

A tibble with origin zip and destination zips (in ranges or unspooled) and the USPS zones the origin-destination pair corresponds to.
