[Feature] Add an optional command before and after image capture

[ddmmcz]

Hello. Thank you for a great plugin.

I have one idea for improvement. I often print in lower light conditions or at night and nothing is visible in the image. I have lighting on my printer which I control via gpio pins with commands from Octoprint. So I was thinking that a few seconds (optional) before taking the photo, the plugin would send the optional command "gpio write 1 1" (turn on lighting) take the photo and then send the optional command "gpio write 1 0" (turn off lighting). Is it possible to add this in the future?

Thank you for the reply.

I think that shouldn't be too miuch work. But instead of implementing just your usecase, I would prefer a more generic solution. So I thought about adding pre-/post bash script hooks which execute custom, user written bash scripts before/after a message is sent. Would that work for you?
