fasthttp allows newlines (\n) between the chunk size and the CRLF (i.e. in the chunk extension). This can cause request smuggling issues with some reverse proxies. This PR prevents this potential vulnerability by disallowing newlines in the chunk extension.
I've also corrected two unescaped carriage returns in error messages which messed with the output formatting.
