This reverts most of commit 0e5176a4477d369a380e1d5a89d53f3b2834f966.
An unrelated filename fix (removing "zika_" prefix from filenames) was
left unreverted.
The instructions around compression were the result of being misled by
curl's default of not unwrapping Content-Encoding (i.e. it must be
enabled by using the --compression option).
