Wip/gray img bug

[lrosenth]

@tobiasschweizer Please have a look. Implemented

1. Support of palette color TIFFS

2. kakadu v7_A_2

Pleadse note that You have to copy v7_A_2 from the Dropbox to the vendor directory in SIPI

@subotic The build fails on travis because a new Kakadu version is required, but it is not available to travis:

unzip: cannot find or open /sipi/vendor/v7_A_2-01382N.zip

Could you update the Kakadu zip? Thanks!

[subotic]

yes, will do it right away.

I had to update imagemagick to version 7.0.7-8 (with brew on my Mac)

However, I still have a problem with iiid_validator. When I run it, I get:

E           conftest.SipiTestError: IIIF validation failed (wrote /Users/tobi/gitreps/Sipi/test/e2e/sipi.log):
E           Traceback (most recent call last):

This is not related to Sipi at all.

Thank you, Ivan!

Pillow has to be upgraded:

pip3 install --upgrade pillow

[tobiasschweizer]

@lrosenth Ok, I ran the tests and also did some heavy extra load testing for IIIF regions and it works fine!

However, I do not understand the changes you introduced in src/formats/SipiIOTiff.cpp and src/metadata/SipiIcc.cpp. Could you explain them to me?
