Standard imghdr Library

The `standard-imghdr` library is a redistribution of the `imghdr` module, which was formerly part of the Python standard library. It provides functionality to determine the type of an image file based on its header. Maintained by the `python-deadlib` project, this library serves as a compatibility layer for projects that relied on `imghdr` after its deprecation in Python 3.11 and subsequent removal in Python 3.13. The current version is 3.13.0 and it follows an infrequent release cadence focused on maintaining compatibility.
