Log Message:
vv: update to 3.2.

This release correctly applies color profiles to JPEG files.

EXR images with more complex data and display windows are now loaded
correctly.

AgX tone mapping operator: The tone mapping operator for viewing
HDR images can be selected with the new command line option -t. In
addition to the previously available PBR Neutral operator, the AgX
operator is now supported, with two optional looks (golden and
punchy).

With this release, vv is now able to load and properly display CMYK
JPEG images.

Image rotation metadata is now properly read and applied to JPEG
files.

Alpha channel in sixel mode and block mode: Both sixel and block
mode do not support transparency, which was not accounted for
before. The alpha channel is now replaced by a solid background
when these modes are active.

Image data emitted in sixel mode is now compatible with a much
wider variety of terminal emulators, at the expense of lower image
quality. Terminal capability checks have been extended to include
more terminals with sixel support.
