Arguments

:: Int

Compression level (Use 9 if uncertain)

-> Bytes

Bytes to compress

-> ByteArray

Use HC compression to produce a frame with a single block. All optional fields (checksums, content sizes, and dictionary IDs) are omitted.

Note: Currently, this produces incorrect output when the size of the input to be compressed is greater than 4MiB. The only way to correct this function is to make it not compress large input. This can be done by setting the high bit of the size. This needs to be tested though since it is an uncommon code path.
