v2.0.0 — {version_tuple} write + onbuild placeholder, et alii

- The `{version}` placeholder in the "basic" `format` step has been renamed to `{base_version}`.  The old name remains usable, but is deprecated.
    - **Breaking**: The `version` argument passed to `Versioningit.do_format()` and `format` method callables has been renamed to `base_version`.
- A `{version_tuple}` field, along with the fields available in the `format` step, is now available for use in templates in the `write` and `onbuild` steps.
    - New step and subtable: "template-fields"
    - **Breaking**: The `version` arguments passed to `Versioningit.do_write()`, `Versioningit.do_onbuild()`, `run_onbuild()`, and `write` & `onbuild` method callables have been replaced with `template_fields` arguments
    - Added a `get_template_fields_from_distribution()` function for use by callers of `run_onbuild()`
- `Versioningit.get_version()` now takes optional `write` and `fallback` arguments
- The `onbuild` step is no longer run when building from an sdist; the configuration therefore no longer needs to be idempotent
- Drop setuptools runtime dependency
    - setuptools is only needed for `get_cmdclasses()`, which should only be called in an environment where setuptools is already installed.
- Prevent log messages from being printed twice under recent versions of setuptools
- Values supplied for the `require-match` parameters of the `tag2version` and `onbuild` steps must now actually be booleans; previously, values of any type were accepted and were converted to booleans.
- Added a `Versioningit.run()` method that returns a structure containing all intermediate & final values
- "git" method: `{author_date}` and `{committer_date}` are no longer "clamped" to less than or equal to `{build_date}`.  This undocumented behavior was based on a misinterpretation of the `SOURCE_DATE_EPOCH` spec, and was even applied when `SOURCE_DATE_EPOCH` was not set.
- When resolving entry points, if multiple entry points with the given group & name are found, error instead of using the first one returned
