## Description
Fixes#5625
When `convert.never_convert_lossy_files` is enabled, `beet convert` was
ignoring the explicit `--format` option and just copying the lossy files
without
transcoding them. For example:
- `beet convert format:mp3 --format opus`
would still produce MP3 files instead of OPUS.
Change:
- Allows to override options `never_convert_lossy_files`, `max_bitrate`
or `no_convert` for `beet convert` as well as trying to convert to the
same format as existing already with a new option `--force`. That way,
for example lossy files selected by the query are transcoded to the
requested format anyway.
- Keeps existing behavior for automatic conversion on import (no CLI
override there).
- Adds tests to cover checking whether `--force` correctly overrides
settings or CLI options.
- Documents the behavior in the convert plugin docs

* Replace `noqa` comments in `assert...` method definitions with
a configuration option to ignore these names.
* Use the `__all__` variable to specify importable items from the
module, replacing `*` imports and `noqa` comments for unused imports.
* Address issues with poorly named variables and methods by renaming
them appropriately.
External Python packages interfacing beets may want to use an in-memory
beets library instance for testing beets-related code.
The `TestHelper` class is very helpful for this purpose.
Previously `TestHelper` was located in the `test/` directory.
Now it is part of `beets` itself (`beets.test.helper.TestHelper`) and
can be easily imported.
