Replace `spelling` usage with types and names

[diivm]

Currentlly, in many instances, .spelling property is used (for checks, types, etc.)

Ex: https://github.com/divmadan/pcl/blob/327830713062dfc7a5044710d17ebe62930c6c1c/bindings/python/scripts/parse.py#L103-L104

Can be replaced like:

if cursor.type != clang.TypeKind.INVALID:
        parsed_info["element_type"] =  cursor.type.kind.name

---

• Why spelling -> name?
  • Much better, as TypeKind's internal __repr__ also uses name
  • Example resultant JSON diff:

  • "element_type": "FLOAT"
  • "element_type": "Float",
