If a complex literal had a negative real part and a positive imaginary
part, it was not parsed properly because the imaginary part also came out
negative.
Includes a test of complex parsing, which fails without this fix.

Prior to this commit, complex("j") would return 0j, and complex("nanj")
would return nan+0j. This commit makes sure "j" is tested for after
parsing the number (nan, inf or a decimal), and also supports the case of
"j" on its own.

This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py. The basics/ subdirectory is excluded for now so we
aren't changing too much at once.
In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.

False/True should be implicitly converted to 0/1 when compared with numeric
types.

NaN may have the sign bit set but it has no meaning, so don't print it out.

This returns a complex number, following CPython behaviour. For ports that
don't have complex numbers enabled this will raise a ValueError which gives
a fail-safe for scripts that were written assuming complex numbers exist.

IEEE floating point is specified such that a comparison of NaN with itself
returns false, and Python respects these semantics. This patch makes uPy
also have these semantics. The fix has a minor impact on the speed of the
object-equality fast-path, but that seems to be unavoidable and it's much
more important to have correct behaviour (especially in this case where
the wrong answer for nan==nan is silently returned).

This is intended to improve coverage of the test suite.
