Could use regex (we already `import re`) to make this more streamlined:
```
m = re.search(r"Features\s*: (.*)\n", cpuinfo)
feature_list = m.group(1).split()
```
This would also lend itself to future extension to include all processors
features by using `re.findall()` and creating a union set of all processor
feature lists.
