Use mode parameter instead of deprecated direction

[mauritsvanrees]

Fixes #102

I noticed that test.pt still used the deprecated direction='contain'. It did work, turning a landscape image into a square:

With the newer mode="contain" the result would not have been so good, basically ignoring the setting:

With this PR, the newer spelling works too.

@mauritsvanrees thanks for creating this Pull Request and helping to improve Plone!

TL;DR: Finish pushing changes, pass all other checks, then paste a comment:

@jenkins-plone-org please run jobs

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass, but it takes 30-60 min. Other CI checks are usually much faster and the Plone Jenkins resources are limited, so when done pushing changes and all other checks pass either start all Jenkins PR jobs yourself, or simply add the comment above in this PR to start all the jobs automatically.

Happy hacking!

The gh-actions pass. Now I test these two PRs together:

https://github.com/plone/plone.scale/pull/66
https://github.com/plone/plone.namedfile/pull/130

They are not dependent on each other, but they change similar things, so it is good to test them in combination.

The Jenkins tests were failing for plone.restapi. Let's hope that is because of the plone.scale changes. Otherwise we should revert temporarily.

I have reverted the merge. I will open a new PR.
