Build failure on Python 3.14

[sarahec]

While building for Python 3.14 on nixpkgs:

ewf_data = <_io.BufferedReader name='/nix/var/nix/builds/nix-build-python3.14-dissect-evidence-3.12.drv-0/b/source/tests/data/ewf.E01'>

    def test_ewf(ewf_data: BinaryIO) -> None:
        e = ewf.EWF(ewf_data)
    
        assert e.size == 4097
>       assert e.open().read(4097) == (b"\xde\xad\xbe\xef" * 1024) + b"\n"
               ^^^^^^^^^^^^^^^^^^^

Could be related to limited 3.14 support at this moment: fox-it/dissect.target#1390

[Schamper]

I was aware of this too. Not quite related to fox-it/dissect.target#1390 but #42 seems to fix this.

Interestingly enough the tests still fail for ASDF on Windows 3.14, but that'll be tackled in another PR :)
