py-yapf: updated to 0.32.0

0.32.0
Added
- Look at the 'pyproject.toml' file to see if it contains ignore file information
  for YAPF.
- New entry point `yapf_api.FormatTree` for formatting lib2to3 concrete
  syntax trees.
- Add CI via GitHub Actions.
Changes
- Change tests to support "pytest".
- Reformat so that "flake8" is happy.
- Use GitHub Actions instead of Travis for CI.
- Clean up the FormatToken interface to limit how much it relies upon the
  pytree node object.
- Rename "unwrapped_line" module to "logical_line."
- Rename "UnwrappedLine" class to "LogicalLine."
Fixed
- Enable `BLANK_LINE_BEFORE_NESTED_CLASS_OR_DEF` knob for "pep8" style, so
  method definitions inside a class are surrounded by a single blank line as
  prescribed by PEP8.
- Fixed the '...' token to be spaced after a colon.
