updated tifffile requirements

Fixes Failing Dailies

I would vote against putting a ceiling on tifffile. Reasons:

1. Writing is not a central part of this library. It is nice to have but not central. Newer versions of tifffile offer new capabilities that I think we should not let it pass (what is a good word for it?).
2. We can use imwrite instead to accomplish the same goal. The specific function that we are using for writing was deprecated but the general writing functionality was not:

Fair enough. tifffile v2018.10.18 doesn't have imwrite, but v2018.11.6 and onward does.

Yeah, I think we should probably drop the writing aspect as we don't use it and it is just one more thing to maintain.

Yes...one of the many things I fixed in my roiextractors 0.6.0 PRs...

Oh, great, I did not know it was on the works. Are those PRs only in your system or is it here?

Not exactly sure what you mean, but you can see I removed write_imaging in #365

[h-mayorquin]

here means the repo so the answer is yes. Thanks
