Update yapf to 0.31.0

[pyup-bot]

This PR updates yapf from 0.28.0 to 0.31.0.

Changelog

0.31.0

Added
- Renamed 'master' brannch to 'main'.
- Add 'BLANK_LINES_BETWEEN_TOP_LEVEL_IMPORTS_AND_VARIABLES' to support setting
a custom number of blank lines between top-level imports and variable
definitions.
- Ignore end of line ` copybara:` directives when checking line length.
- Look at the 'pyproject.toml' file to see if it contains style information for
YAPF.
Changed
- Do not scan exlcuded directories. Prior versions would scan an exluded
folder then exclude its contents on a file by file basis. Preventing the
folder being scanned is faster.
Fixed
- Exclude directories on Windows.

0.30.0

Added
- Added `SPACES_AROUND_LIST_DELIMITERS`, `SPACES_AROUND_DICT_DELIMITERS`,
and `SPACES_AROUND_TUPLE_DELIMITERS` to add spaces after the opening-
and before the closing-delimiters for lists, dicts, and tuples.
- Adds `FORCE_MULTILINE_DICT` knob to ensure dictionaries always split,
even when shorter than the max line length.
- New knob `SPACE_INSIDE_BRACKETS` to add spaces inside brackets, braces, and
parentheses.
- New knob `SPACES_AROUND_SUBSCRIPT_COLON` to add spaces around the subscript /
slice operator.
Changed
- Renamed "chromium" style to "yapf". Chromium will now use PEP-8 directly.
- `CONTINUATION_ALIGN_STYLE` with `FIXED` or `VALIGN-RIGHT` now works with
space indentation.
Fixed
- Honor a disable directive at the end of a multiline comment.
- Don't require splitting before comments in a list when
`SPLIT_ALL_TOP_LEVEL_COMMA_SEPARATED_VALUES` is set. The knob is meant for
values, not comments, which may be associated with the current line.
- Don't over-indent a parameter list when not needed. But make sure it is
properly indented so that it doesn't collide with the lines afterwards.
- Don't split between two-word comparison operators: "is not", "not in", etc.

0.29.0

Added
- Add the `--quiet` flag to suppress output. The return code is 1 if there are
changes, similarly to the `--diff` flag.
- Add the `indent_closing_brackets` option. This is the same as the
`dedent_closing_brackets` option except the brackets are indented the same
as the previous line.
Changed
- Collect a parameter list into a single object. This allows us to track how a
parameter list is formatted, keeping state along the way. This helps when
supporting Python 3 type annotations.
- Catch and report `UnicodeDecodeError` exceptions.
- Improved description of .yapfignore syntax.
Fixed
- Format subscript lists so that splits are essentially free after a comma.
- Don't add a space between a string and its subscript.
- Extend discovery of '.style.yapf' & 'setup.cfg' files to search the root
directory as well.
- Make sure we have parameters before we start calculating penalties for
splitting them.
- Indicate if a class/function is nested to ensure blank lines when needed.
- Fix extra indentation in async-for else statement.
- A parameter list with no elements shouldn't count as exceeding the column
limit.
- When splitting all comma separated values, don't treat the ending bracket as
special.
- The "no blank lines between nested classes or functions" knob should only
apply to the first nested class or function, not all of them.
