zcash_proofs: Add API for downloading the Sapling parameters Includes an example that exposes the API as a binary.

fn main() -> Result<(), minreq::Error> {
Download sprout parameters in zcash_proofs (#459) * Download sprout parameters in-memory * Add download_sapling_parameters and deprecate download_parameters * This avoids confusion between sprout and sapling downloads, while maintaining backward compatibility. * Download a single file, rather than parts * This is more efficient, because TCP adjusts its transfer speed in the first ~20 seconds of each new connection. * Only download files if needed, but always check the hashes * Allow the caller to specify a response timeout * Stream downloads from server to disk * Refactor file loads to use the same verifying function as downloads * Check file sizes to help debug parameter load failures * Remove downloaded files on error (but leave existing files alone) * Add a sprout and sapling download example * Move the download Read impl into its own module * Derive standard traits on SaplingParameterPaths * Require features for the load parameters method
