Jonas Jenwald 505f15f221 Avoid accidentally getting the entire font file in readNameTable (issue 7020) ...

In the PDF file in question, some of the 'name' table entries have `record.length === 0`. This becomes problematic in the non-unicode case, since `font.getBytes(0)` will fetch the *entire* stream.
Given that OTS rejects 'name' entries larger than `2^16`, this thus explain the sanitizer errors.

Fixes 7020.
