Inkex-bh

create-inset

- Fix to work when there are visible clones of layers with hidden parents. ([2])

update-symbols

- Only skip symbol sets if they contain a symbol id that conflicts
with an already scanned symbol set. Standard-scale (48:1) symbols
sets are loaded first, so this results in skipping non-standard
symbol sets, but *only* if they contain conflicting symbol ids.
Previously, we just ignored all non-standard symbol sets.

(Until recently, bale sets for non-standard scales (e.g. 60:1) used
the same symbol ids as the standard scale (48:1) sets. As of
`bh-symbols==1.0.0rc5`, all symbols now have globally unique ids.)

- Do not update unchanged symbols.

- Add `dry-run` option to report which symbols would be updated.

- Report the currently installed version of [bh-symbols].

- Added new *update-symbols* extension to update the symbol definitions
in a drawing to those in the installed version of the [bh-symbols] symbol
library.

**NOTE** The *update symbols* operation, if it goes badly, has the
capability to significantly mangle the drawing. Make sure you have
a back-up copy of the drawing before running the extension.

Refactor

- Use helpers provided by `inkex.command` (rather than calling
`subprocess.run` directly) to run Inkscape (and optipng) from the
*create-inset* extension.

Testing

- Add integration test for the *create-inset* extension. This checks
that the extension can be invoked from Inkscape's batch mode.

- Omit use of virtual environment in `test_run_module_in_installed_extensions`.

Bugs

- Fix the _create inset_ extensions when running from the AppImage-packaged version
of Inkscape 1.2.2.

Bugs

- Fix the _create inset_ and _hide rats_ extensions so that they might
actually run under Inkscape 1.0.x.

Packaging

- We now build and publish — as GitHub Release artifacts — zip
archives of the extension that suitable for unzipping in a user's
Inkscape extensions directory.

- Use [hatch] for packaging.

Testing

- Install `inkex` from custom-built wheels in the python registry at
https://gitlab.com/dairiki/inkex/. The versions of `inkex` on PyPI
are stale, and also don't match the `inkex` included in any
particular version of Inkscape.

- We now test (I think) under truly the whole matrix of supported
python × Inkscape/inkex versions.
