openbim-step 0.6.2

Added

• SchemaGraph::resolve_complex (#5): resolves a complex entity instance
  (#1=(A(..)B(..)C(..));, the Part 21 external mapping, ISO 10303-21:2016
  §12.2.5.3) against the schema. Returns a ComplexLayout with one
  ComplexPart per partial record, each holding only the explicit
  attributes its own entity declares (not the inherited ones, unlike
  attributes), plus the instance's full supertype closure in types.
  ComplexSlot::is_derived marks slots another type in the instance
  redeclares as derived, which a conforming file writes as *.
• ComplexIssue: unknown partial types, partial records out of ascending
  name order, repeated partial records, and supertypes missing their own
  partial record are reported, never silently accepted. Parts that resolve
  are still returned alongside the issues.

Checked against the real data: all 314 complex instances in OCCT's AP214
test files linkrods.step (255) and screw.step (59) resolve against
AP214e3 with no issues and slot counts equal to parameter counts, and every
* falls in a slot marked derived.
