While we're mucking around with imports, we might as well formalize the
style we use. Let's use isort to do it for us.

lines_after_imports=2: Use two lines after imports, to match PEP8's
desire to have "two lines before and after" class definitions, which are
likely to start immediately after imports.

force_sort_within_sections: Intermingles "from x" and "import x" style
statements, such that sorting is always performed strictly on the module
name itself.

force_grid_wrap=4: Four or more imports from a single module will force
the one-per-line style that's more git-friendly. This will generally
happen for 'typing' imports.

multi_line_output=3: Uses the one-per-line indented style for long
imports.

include_trailing_comma: Adds a comma to the last import in a group,
which makes git conflicts nicer to deal with, generally.

line_length: 72 is chosen to match PEP8's "docstrings and comments" line
length limit. If you have a single line import that exceeds 72
characters, your names are too long!
