Moving source directory to src/anndata

[ivirshup]

Reasoning

• Nice consistent relative positioning in the editor side bar
• Much harder to accidentally import from the code rather than installed version
• Consistent with cookie cutter

Transition guide

• All devs will need to rm -r their old anndata directory. There will be a _version.py file there + empty directories. I believe conftest.py tried to import from it.

Uhh, works on my machine?

If I try to run the tests in a fresh clone, but using my old install, I can reproduce. Editable install of fresh clone then running the fresh clones tests works.

Probably not following this up much more tonight.
