Function scoreFormula

scoreFormula(candidate: string): number
Scores how "formula-like" a candidate is, so the best of several matches can be chosen. Favors more element symbols first (a real formula packs several), then the presence of a subscript/count, then raw length — so NaOSOCH3 outranks a two-letter coincidence such as IN (from "EINECS") or CS pulled out of surrounding codes/prose.
Parameters
- candidate: string
  A raw formula match.
Returns number
A numeric score; higher is more likely to be a real formula.
Example
```
scoreFormula("NaOSOCH3") > scoreFormula("IN"); // true
```
