/* Decompresses an LZ4F image (multiple LZ4 blocks with frame header) from src
* to dst, ensuring that it doesn't read more than srcn bytes and doesn't write
* more than dstn. Buffer sizes must stay below 2GB. Can decompress files loaded
* to the end of a buffer in-place, as long as buffer is larger than the final
* output size. (Usually just a few bytes, but may be up to (8 + dstn/255) in
* worst case. Will reliably return an error if buffer was too small.)
* Returns amount of decompressed bytes, or 0 on error.
