camera_streaming_http monochrome & without jpeg

Enhancement request

Hi there,

please could you add code for monochrome HM01b0?

and skip jpeg compression?

I'm not finding similar code in the wild that might be adapted.
and the code comments currently don't indicate how this might be done.

In particular for more complex use case with models using MLTiny how does one implement in monochrome.

some extra examples or code comments would be helpful

@peepo a grayscale datadump would be useful would be useful.
