README: the linearization checker - #38

Conversation
go-pdfkit/reader v0.10.0 reads and checks a file's linearization (ISO 32000-1 Annex F). The section says what is checked, what is NOT -- the hint tables of F.4, which a file can fail while passing everything here -- and that there is no linearizing writer yet, because the checker came first on purpose: a writer cannot be trusted without one. It also says where the positives come from. They are qpdf's output rather than fixtures written to agree with my reading of Annex F, and on five real library scans judged by `qpdf --check` alongside us the two agree 5 to 0.
