:content
Uncompresses a gzip-format byte string and returns the original content.


`gz_uncompress()` validates the gzip header, CRC32 footer, and uncompressed-size footer. It throws a runtime error when the input is not a supported gzip stream or fails validation.

:example
String packed = gz_compress("round trip data");
print(gz_uncompress(packed), "\n");
