1.  Add `bin/get_size.py` so that `python bin/get_size.py plotly build`    reports the number of files and total size in bytes of the `plotly`    directory (where generated code is put) and the `build` directory    that is populated by `python setup.py build`.1.  Modify `codegen/__init__.py` and `./setup.py` so that    `python setup.py --reformat=false` disables reformatting.1.  Assign an empty string to the `data_docs` field of generated    validators.  (This has a major impact because those docs are    duplicated many times.)1.  Alias name of base validator during import in    `codegen/validators.py`.1.  Remove the long list of CSS colors from help strings for color    properties.1.  Replace `super(Parent, self)` with `super()` in generated code.1.  Drop use of sys.version_info and TYPE_CHECKING.  Removed the check    for Python < 3.7 using `sys.version_info` and as a backup checking    `typing.TYPE_CHECKING`; this saves a little space and also cleans    up the code.1.  Remove mention of Chart Studio and explicit enumeration of system    font names from plotly.js / plot-schema.json so that this text    isn't copied dozens of times into the plotly.py bundle.1.  Introduce `_init_provided()` for `BaseFigure` and `BasePlotlyType`    that calls a helper function `_initialize_provided()` to replace    repetitions of:```_v = arg.pop("something", None)_v = something if something is not None else _vif _v is not None:    self["something"] = _v```Original size of plotly/**/*.py: 42283582 bytesCurrent size of plotly/**/*.py:  31931739 bytesChange: -25%

1.  Modify `commands.py` to run code generation.1.  Remove comments from generated code.1.  Replaced named arguments in constructors with positional arguments.1.  Regenerate all code.Notes:The generated code is reformatted once again: this slightly increasessize but makes it more readable.There is one flaky test:`tests/test_plotly_utils/validators/test_colorscale_validator.py::test_acceptance_named[Inferno_r]`It fails when the entire test suite is run but does *not* fail whenonly `test_colorscale_validator.py` is run (using Python 3.11.9).| branch   | format  | bytes    | %age || -------- | ------- | -------- | ---- || master   | .whl    | 14803768 |      || codegen2 | .whl    | 12215667 | -18% || master   | .tar.gz |  8100014 |      || codegen2 | .tar.gz |  6114458 | -24% |

1.  Update required version of `black` in `pyproject.toml` and `.circleci/config.yml`.2.  Update Python version identifiers in `tool.black` section of `pyproject.toml` to include `py311` and `py312`.3.  Modify invocation of `black` in `commands.py` to format with `py311`.4.  Regenerate and reformat code.

- Add caveat to the top of every machine-generated file to warn people  not to edit them.- Make name of initial value property setter more readable.- Run black formatting with multiple Python versions.
