DEP(deps): Update confuse requirement from ~=1.7.0 to ~=2.0.0

[dependabot]

Updates the requirements on confuse to permit the latest version.

Changelog

Sourced from confuse's changelog.

v2.0.0 ''''''

• Drop support for versions of Python below 3.6.

v1.7.0 ''''''

• Add support for reading configuration values from environment variables (see EnvSource).
• Resolve a possible race condition when creating configuration directories.

v1.6.0 ''''''

• A new Configuration.reload method makes it convenient to reload and re-parse all YAML files from the file system.

v1.5.0 ''''''

• A new MappingValues template behaves like Sequence but for mappings with arbitrary keys.
• A new Optional template allows other templates to be null.
• Filename templates now have an option to resolve relative to a specific directory. Also, configuration sources now have a corresponding global option to resolve relative to the base configuration directory instead of the location of the specific configuration file.
• There is a better error message for Sequence templates when the data from the configuration is not a sequence.

v1.4.0 ''''''

• pathlib.PurePath objects can now be converted to Path templates.
• AttrDict now properly supports (over)writing attributes via dot notation.

v1.3.0 ''''''

• Break up the confuse module into a package. (All names should still be importable from confuse.)
• When using None as a template, the result is a value whose default is None. Previously, this was equivalent to leaving the key off entirely, i.e., a template with no default. To get the same effect now, use confuse.REQUIRED in the template.

v1.2.0 ''''''
