Maps an {@link ReadableByteChannel} or {@link WritableByteChannel} to a URL
for use by Humble.

@param url the url
@param in the input to use
@param out the output to use
@param unmapOnOpen should we remove the mapping as soon as the resulting
handler is opened?
@param closeOnClose should we call {@link Closeable#close()} on the
underlying input or output objects when
{@link IURLProtocolHandler#close()} is called (if supported by the
underlying object)?
@return Returns a URL that can be passed to Humble's {@link Container}'s
open method, and will result in IO being performed on the passed in
streams.
Maps an { @link ReadableByteChannel } or { @link WritableByteChannel } to a URL for use by Humble .
