**BETSE 1.2.2** released.

This minor release brings titillating support for **configuring wrapper
logging** and **runtime type-checking wrapper parameters.**

This minor release resolves **3 issues.** Noteworthy changes include:

## Features Added

* **Wrapper logging configurability.** The high-level
  `betse.science.wrapper.BetseWrapper` class now enables logging to be
  configured at instantiation time. Specifically, the
  `BetseWrapper.__init__` method now accepts these optional
  logging-specific parameters:
  * `log_filename`, the relative or absolute filename of a file to
    append logging messages to. When running BETSE on a cluster, users
    are advised to set this parameter for each process-specific
    `BetseWrapper` instance to a filename isolated to that process.
    Doing so avoids non-deterministic failures when rotating log files,
    including a dreaded non-human-readable `"OSError: [Errno 116]
    Stale file handle"` exception emitted when attempting to log to a
    log file currently being rotated by a competing BETSE process.
  * `log_level`, a string-based enumeration configuring the global
    logging level (e.g., `"ALL"`, `"DEBUG"`, `"NONE"`). If specified,
    this global logging level overrides the optional `verbose` parameter
    accepted by various public methods of the `BetseWrapper` class.
* **Wrapper parameter runtime type-checking.** All parameters passed to
  all `BetseWrapper` methods are now type-checked at runtime via
  [`beartype`](https://github.com/beartype/beartype), a
  performance-friendly third-party pure-Python package.

## Dependencies Added

* **Beartype ≥ 0.10.0.** BETSE now requires a reasonably recent version
  of [`beartype`](https://github.com/beartype/beartype) as a mandatory
  runtime dependency.

## Issues Resolved

* **Fast solver `Dm_cells` export.** BETSE's fast solver now properly
  exports `Dm_cells` as a function of time.

## Deprecations Resolved

* `license_file` -> `license_files` in `setup.cfg`. This release
  resolves a mostly negligible `setuptools` deprecation warning
  concerning the deprecated `license_file` setting in the top-level
  `setup.cfg` file:

     /usr/lib/python3.8/site-packages/setuptools/config/setupcfg.py:508:
     SetuptoolsDeprecationWarning: The license_file parameter is
     deprecated, use license_files instead.

* `numpy.distutil.__config__` -> `numpy.__config__`. This release
  resolves a deprecation warning emitted under NumPy ≥ 1.23.0 when
  importing *anything* from the `numpy.distutil` submodule.
  Specifically, this commit generalizes the `betse.lib.numpy.numpys`
  submodule to preferably import the actively maintained
  `numpy.__config__` submodule under NumPy ≥ 1.23.0 *before* falling
  back to importing the deprecated `numpy.distutil.__config__` submodule
  under NumPy < 1.23.0. Doing so improves the likelihood that BETSE will
  behave as expected under NumPy ≥ 1.24.0, where the deprecated
  `numpy.distutil` submodule is expected to be removed entirely.

## Tests Improved

* **Wrapper testing.** The high-level
  `betse.science.wrapper.BetseWrapper` class against a barrage of
  integration tests, including:
  * `test_wrapper_default()`, exercising that class with default
    parameters running an initialization phase.
  * `test_wrapper_logging()`, exercising that class with various
    non-default logging parameters running an initialization phase.
* **Test suite restructured.** Our test suite has been restructured so
  as to ensure that lower-level unit tests are exercised *before*
  higher-level integration tests -- improving the readability of test
  failures when the former fail.
