Certain types of files in a pyinstaller bundle/binary cause Invalid ELF image: Magic number does not match

[Azathothas]

Hi, if the final pyinstaller binary bundle includes files like :

LICENSE
.conf
#and probably more

staticx will refuse and error out with: Invalid ELF image: Magic number does not match
Running with debug doesn't provide extra information, it's always like this:

---snipped---
DEBUG:root:Extracting to /tmp/staticx-pyi-i4ywqjfy/yaml/_yaml.cpython-312-x86_64-linux-gnu.so
DEBUG:root:Extracting to /tmp/staticx-pyi-i4ywqjfy/zstandard/_cffi.cpython-312-x86_64-linux-gnu.so
DEBUG:root:Extracting to /tmp/staticx-pyi-i4ywqjfy/zstandard/backend_c.cpython-312-x86_64-linux-gnu.so
staticx: /tmp/staticx-pyi-i4ywqjfy/nxc/data/nxc.conf: Invalid ELF image: Magic number does not match
#Fails here

I believe this is related to these issues:
#281
#268

I believe either maintaining a whitelist/blacklist or a more thorough check of the filetype should help.

Just realized, that this may be fixed by #277

Yes, it works. Thank you.
