Subject: [PATCH] Change the `assert` in `Parser.findDefaultInlineStreamEnd` to
 a non-PRODUCTION one

Given that this `assert` is only intended to catch any implementation bugs in our code, and not actually to validate the PDF data directly[1], we can avoid making this function call unconditionally.

---
[1] In those cases, for example a `FormatError` should have been thrown instead.
