:content
Compresses `src` and returns a gzip-format byte string.

The result is binary data. Store it in a file, send it with an appropriate content type/encoding, or pass it directly to `gz_uncompress()`.


UCE writes a standard gzip wrapper around a deflate stream, including CRC32 and uncompressed-size footer fields.

:example
String original = "hello hello hello hello hello";
String packed = gz_compress(original);
print(original.length(), " bytes -> ", packed.length(), " bytes; restores to: ", gz_uncompress(packed), "\n");
