Brotli body decompression can be corrupted

[jcamiel]

Given a HTTP binary response compressed with brotli, that is greater than 4096 bytes, the automatically decompressed body will be corrupted when using --compressed option.

For instance, with the attached jpg image compressed with brotli, if we try to decompress it automatically:

$ echo 'GET http://localhost/cat.jpg.br' | hurl --decompressed > /tmp/cat.jpg

We get a corrupted jpg file back.

There is a wrong assumption in the code that the HTTP body response is less than 4096 bytes:

hurl/packages/hurl/src/http/content_decoding.rs

Lines 101 to 104 in 16f501d

	let mut reader = brotli::Decompressor::new(data, 4096);
	let mut buf = [0u8; 4096];
	let n = match reader.read(&mut buf[..]) {
	Err(_) => {

cat.jpg.br.zip
