Bumps python-magic from 0.4.15 to 0.4.21.

Changelog

Sourced from python-magic's changelog.

Changes to 0.4.21

• Unify dll loader between the standard and compat library, fixing load failures on some previously supported platforms.

Changes to 0.4.20

• merge in a compatability layer for the upstream libmagic python binding. Since both this package and that one are called 'magic', this compat layer removes a very common source of runtime errors. Use of that libmagic API will produce a deprecation warning.

• support python 3.9 in tests and pypi metadata

• add support for magic_descriptor functions, which take a file descriptor rather than a filename.

• sometimes the returned description includes snippets of the file, e.g a title for MS Word docs. Since this is in an unknown encoding, we would throw a unicode decode error trying to decode. Now, it decodes with 'backslashreplace' to handle this more gracefully. The undecodable characters are replaced with hex escapes.

• add support for MAGIC_EXTENSION, to return possible file extensions.

• add mypy typing stubs file, for type checking

Changes in 0.4.18

• Make bindings for magic_[set|get]param optional, and throw NotImplementedError if they are used but not supported. Only call setparam() in the constructor if it's supported. This prevents breakage on CentOS7 which uses an old version of libmagic.

• Add tests for CentOS 7 & 8

Changes in 0.4.16 and 0.4.17

• add MAGIC_MIME_TYPE constant, use that in preference to MAGIC_MIME internally. This sets up for a breaking change in a future major version bump where MAGIC_MIME will change to mathch magic.h.

• add magic.version() function to return library version

• add setparam/getparam to control internal behavior

• increase internal limits with setparam to prevent spurious error on some jpeg files

• various setup.py improvements to declare modern python support

• support MSYS2 magic dlls

• fix warning about using 'is' on an int in python 3.8

• include tests in source distribution

• many test improvements:
