[libcamera-devel] [PATCH 0/2] Improve BayerFormat class

[Sebastian Fricke]

This patch series adds unit-tests and the `fromV4L2PixelFormat` method
to the BayerFormat class.

I also wanted to discuss one alternative that I played around with.
We could maybe drop one of the two mapping tables and use the following
logic to get the map key from a mapped value.

```
#include <algorithm>
...
BayerFormat BayerFormat::fromV4L2PixelFormat(V4L2PixelFormat v4l2Format) const
{
    auto it = std::find_if(
        bayerToV4l2.begin(),
        bayerToV4l2.end(),
        [v4l2Format](const auto& i) { return i->second == v4l2Format; }
    );
    if (it != bayerToV4l2.end())
        return it->first;

    return BayerFormat();
}
```
