Brotli annoyingly lacks magic bits/headers making content-sniffing it quite difficult. We now employ multiple heuristics including: - checking for errors reading the first 16 bytes - checking to see if the decompressed data exists in the input stream - reading in chunks of 16 bytes up until 128 bytes have been read, checking for errors that would indicate a corrupt archive (which we can infer is us actually trying to decompress non-brotli data)
