Inline image token value ends with EI, not delimiter

The inline image token erroneously included the delimiter that
followed EI. The ObjectHandle created from it was correct.

* Bug fix: when returning an inline image token, the tokenizer no
longer includes the delimiter that follows EI. The
QPDFObjectHandle created from the token was correct.
* Handle files with direct page objects, which is not allowed by
the PDF spec but has been seen in the wild. Fixes #164.
