        public static ContentType determineCT​(java.lang.String contentTypeStr,

                                      java.lang.String target)

        Determine the content type to be used, given the target URL, the content-type from Content Negotiation and a hint language. This is a pragmatic balance. A content-type of "text/plain" is ignored - it is too often wrong.

        The decision is

        Content type (but not text/plain) > hint > file extension.
        We make content type (via content negotiation) strongest because a server may return something unexpected because that is all it can do. We are assuming servers don't lie. The "hint" is really a hint just for file extension override.

        In the case of no file extension, this reduces to the hint being the default choice if conneg does not produce anything useful.

        Parameters:
        contentTypeStr - Content-Type string
        hintLang - Default language
        target - The URL of the target (file extension may be used)
        Returns:
        ContentType or null
