<pre>
The uncompressed threat entries in hash format.
Hashes can be anywhere from 4 to 32 bytes in size. A large majority are 4
bytes, but some hashes are lengthened if they collide with the hash of a
popular URI.

Used for sending ThreatEntryAdditons to clients that do not support
compression, or when sending non-4-byte hashes to clients that do support
compression.
