label is not ascii errors with hostnames containing utf8 characters

This library here

Lines 75 to 77 in 1912667

    
           if !parse_data[pos+1..end].is_ascii() { 
        
               return Err(Error::LabelIsNotAscii); 
        
           }

returns a LabelIsNotAscii error when it encounters queries or answers with label or hostnames containing utf8 characters.

With "normal" DNS queries, utf8 characters are converted to puny code. Multicast DNS queries have the exact same structure except they allow ascii or utf8 characters.[1]

I don't know if it's within the scope of this project. If it is, I believe that line should be changed to allow any utf8 encoded string.

The same question！

	if !parse_data[pos+1..end].is_ascii() {
	return Err(Error::LabelIsNotAscii);
	}
