Many scancode dependencies are broken for Mac M1

### Description
This is not necessarily a bug with Scancode, but a handful of the required dependencies are broken and cannot install on Mac M1 platform. This is a huge blocker for anyone using this platform as it is impossible to install scancode using pip. Perhaps the scancode docs should be updated to note that scancode is not usable on this platform?

### How To Reproduce
Try to install scancode on Mac M1 computer. In my case, I am running Ubunutu VM using fusion but the same issues arise when I try to install scancode directly on my mac shell (not in a fusion VM).
```
(ternenv) rose@rose-vm:~/ternenv/tern$ pip install --upgrade pip setuptools wheel
(ternenv) rose@rose-vm:~/ternenv/tern$ pip install scancode-toolkit
```

Specific libraries with issues installing:
bitarray intbitset lxml pyahocorasick pycryptodome cffi
