Issue 20

[turekg]

Ready to merge, works with Tensorflow 1.14 and CSBDeep 0.4.0.

I tested it with python 3.7 and tensorflow-gpu==1.14 and it works. Additionally I tested python 3.6 and tensorflow-gpu==1.12 and this works too.

Could you add this information to the readme and also include this configuration in the travis.yml file?

Thank you for refactoring and making N2V compatible with csbdeep-0.4.0!

All fixes regarding #20 are in place. Thank you @turekg !

In discussions with @alex-krull and @fjug we figured out that we also need channel-wise normalization #32 and a super-conservative mode #33 could be beneficial.

@fjug and I will work on that next week.

I think it makes sense to add these features/fixes also to this PR and then make one new release with all changes. Object if you think otherwise :)

[tibuch]

I just read about short change logs/PRs. Since #32 and #33 have nothing to do with #20 I will merge this PR and release N2V v0.1.7.

Thank you @turekg for the PR.
