icc: Add flags for writing and dumping profiles

Browse Source 
This adds three flags to icc:

* --reencode-to=<file> re-serializes a profile to a given file,
  using Gfx::ICC::encode(). This is mainly useful for testing that
  code.

* --dump-to=<file> dumps the raw ICC profile bytes read from the
  input to disk. This is useful for extracting ICC profiles from
  images, and for comparing the raw profile bytes to the profile
  bytes written by --reencode-to=.

If either of these flags is passed, icc by default no longer dumps
the icc data to stdout. To force priting of the data even if either
of these flags is present, this also adds:

* --print, which forces printing ICC contents, even if either or
  both of the icc-data writing flags are present.
