Fuzzing found a few more stack overflows. Let me fix them before merging this. |

Oh dear, thanks for this though! I'm happy to merge when you feel this is ready, though |
Raphael Salas found more stack overflows involving very large symbols that failed while the parser was trying to skip over tokens. These are fixed by moving the recursion limiter from the printer to the parser, and updating the printer to use the parser's limiter. The failing cases are added as unit tests.

I'm submitting this for review while I run the fuzzer overnight.
