Lynne a964dc4fc7 lavc: add a Panasonic RW2 decoder
Supports RawFormat 8, used by the S1II, S5II and GH6. Outputs the Bayer
mosaic, with the sensor borders as cropping and the black and white
levels as raw color params side data.

The as-shot white balance (tags 0x24 - 0x26) is exported as
AVRW2RawColorParams, and the TIFF and EXIF tags of IFD0 and its sub-IFDs
as EXIF side data, gathered during the single header walk and attached
without re-parsing. The orientation becomes a display matrix; Panasonic's
raw parameters, the previews and the strip pointers are left out.

The whole file is given as one packet.

Bit-exact with LibRaw on 801 S1II files, at 3x its speed per thread.
