NIM compiled binaries fail to parse section.

This issue can be replicated with creating a simple nim program, for eg.
echo "Hello World"
and compiling it with on linux:
nim c --app=console -d:exe -d:mingw --cpu=amd64 -d:debug -d:strip -d:exe --out=helloworld.exe helloworld.nim
scan with avred results in following output:
╰─ python3 ./avred.py --file helloworld.exe ─╯

KeyError: 'scanSpeed'
Any other file types work as expected.

It actually didnt even depend on nim compiled exes, but was just bad coding on my part. Can try again.

It is not the matter of dependence on nim compiled exes, but the error of detecting sections of nim compiled exes:
PE32+ executable (console) x86-64, for MS Windows, 20 sections

The fix does not crash the program now, but the issue remains the same.

What exactly is the issue?
- Is avred crashing?
- Is the binary misidentified? NIM compiled exe's should be PE32
- Do the sections not get identified? Are some missing?
I compiled and uploaded your example, looks alright to me: https://avred.r00ted.ch/file/qCJRKw.nim.exe
