HPDFHeadlessReadObjectStreamIndex
HPDFHeadlessReadObjectStreamIndex(Dictionary, DecodedBytes, MaxObjects, MaxDecodedBytes, CancellationToken) in HPDFHeadlessXRef returns THPDFHeadlessObjectStreamMembers for a direct Type=ObjStm dictionary
Positive object and decoded-byte limits bound the header and payload; direct N and First values and numeric header pairs are parsed through the shared parser, with duplicate numbers, invalid offsets, and mismatches rejected
The optional cancellation token defaults to nil; dictionary and byte-buffer ownership stays with the caller, and errors raise EHPDFHeadlessXRefError or the shared parser's budget exception
