[Feature-Request] expose sharpness setting in the ROS driver

[abaeyens-imod]

why

When currently using the Luxonis cameras with the ROS driver, the default sharpness is set quite high and not adjustable. We would prefer that it can be set lower to avoid the current oversharpening artefacts and the amplified image noise.

what

• A new parameter sharpness that adjusts the sharpening.
• This parameter doesn't have to be dynamic.
• We would appreciate seeing this also for Noetic.

how

At first sight: this setting is already available in the C++ API, so it's mostly a matter of exposing it in the ROS driver.

also

If possible, also expose the parameters luma_denoise and chroma_denoise.
