[NUT-devel] [RFC] add Bayer fourccs

[Peter Ross]

---
Hi. Here is my stab at assigning fourcs for Bayer pixel formats.

I've used character 0xBA to identify Bayer formats, followed by the top
component order and bit-depth. A 7-bit ASCII value would probably be
better. Ideas/suggestions welcome.

 Since many exotic planar YUVA pixel formats are not contemplated by
 the AVI/QuickTime FourCC lists, the following scheme is adopted for
