JEITA EXIF color space defines and supports two color spaces only per
the JEITA specification: sRGB and AdobeRGB1998.

The PIEX C++ returns their values as strings 'sRgb' and 'adobeRgb' so
return those values in the PiexLoaderResponse [1].

Note JEITA EXIF color space indicates the color space only. The image
does not have an embedded ICC Color Profile. A future option for piex
is to slice open the JPEG preview, insert an ICC Color Profile in the
AdobeRGB1998 case, before returning the PiexLoaderResponse.

[1] In files app, make image_request_task.js convert the value in the
PiexLoaderResponse to ColorSpace type. No change in behavior.
