Description
---
Support the ChemDraw representation: a node of type `MultiAttachment` whose `Attachments` property lists the member atoms, with the bond to the central atom being an ordinary bond. Ferrocene is the vendor specification's own example of this.
Three pieces of work: the CDXML (text) path; the binary CDX path, which needs the missing reader and writer cases for the `CDXObjectIDArrayWithCounts` data type (a leading UINT16 count followed by UINT32 ids); and writing the node out. `VariableAttachment` must not be misread as haptic.
**Done when:** a structure with a multi-attachment node load from both CDXML and binary CDX and roundtrips.
