release before publishing the blog post

[keewis]

With pint=0.19 out we can hopefully publish the blog post very soon (I mean, I guess I said that a few months ago as well, but this time it's hopefully true). There are a few issues we should try to fix first:

• dequantifying destroys multiindex #164
• Can .pint.magnitude return a DataArray instead? #151 most likely rejected
• Raise pint.DimensionalityError instead of ValueError #144 (postponed to a later release)
• where operation on quantified gives RecursionError #136 (this is a bug in pint)
• Calling quantify() on already-quantified data arrays #47 / use .pint.quantify() as a identity operator #175
• Example docs / notebook #2 would also be good to have, but I guess that's a bit more work?

I think there is another problem: compatibility with pint's master branch.

I tried updating my PRs to use the master version of pint just now and I'm getting import errors saying that from pint.quantity import Quantity won't work because pint appears to have made internal changes that mean there is no longer a module named quantity. (Perhaps I should make a new issue for this?)

I think that with #151 possibly no longer wanted, #175 ready to merge, and leaving #2 for later, aren't we ready to release?

it seems like #177 slightly broke the index page, I'll try to figure out why that happened and release afterwards

I've just published the release 🎉

It should be on PyPI by now, and will soon be on conda-forge once that picks it up.
