96-bit identifier of the Go library rs/xid. It uses the MongoDB ObjectId layout (a 4-byte time in seconds, a 3-byte machine ID, a 2-byte process ID and a 3-byte counter) and writes the 12 bytes as 20 characters of lowercase base32hex (digits and the letters a to v), which keeps the sort order. The last character holds a single bit, so it is 0 or g.
