Flag "few" used when it should be "a few"

## Description

This is extremely common among Arabic speakers no matter how good their English is, but I'm pretty sure others make it too.

"Few" has the implication of "hardly any", insufficient, not enough, so tends negative.
"A few" on the other hand tends positive as in "better than nothing" or "not a lot but probably enough".

## Potential False Positives

I imagine it will be quite difficult to design heuristics to detect this.

No source file, test, or entry point is named. Start by locating how the grammar checker handles “few” and review the linked examples and references; define heuristics that distinguish “few” from “a few,” including the listed potential false positives. Done means the intended examples are detected without incorrectly changing valid uses.
