Add GREY pixelformat

[gudvinr]

Fixes #170

Monochrome cameras send only Y component of YUV image

[gudvinr]

I think that instead of writing same luma value into RGB components it might be beneficial to just use JCS_GRAYSCALE and encode into 8-bit image instead to save size but I am not sure how it would work here.

@drowningblue can you please test this PR?

@mdevaev can you review this PR? I rebased on top of latest release.

Looks fine for me, just replace type names. And we need a testing.

[drowningblue]

Sorry it took me awhile, I am a total noob here. But it is working, thank you. I have a stream!

One small thing to note is GREY under formats is missing in --help

Thank you both again! @gudvinr @mdevaev

Done.

It works with my oCam, I see the stream.

@mdevaev I doubt you have a camera that can output GREY but I think v4l2loopback can do this, so if you want or need to verify it yourself before pulling, it might be a good choice.

[mdevaev]

@gudvinr I believe you :D
