parse

Parse the decoded content-stream bytes into a flat list of operations.

Recovery (MuPDF parity, north-star gate #1): a single malformed operand or operator must NOT abort the whole page. Any exception thrown while reading a token/object is caught, the offending byte(s) are skipped, and parsing resumes at the next operator. Forward progress is guaranteed: every catch path advances the reader past the position where the failure was observed, so a stubbornly-bad byte can never spin the loop.
