Fix maximum recursion depth exceeded

[hlky]

Fix for error encountered when compiling large graph. This PR simply increases the recursion limit in compiler/stable_set.py.

RecursionError: maximum recursion depth exceeded while calling a Python object

[hlky]

Just for further context, this issue was encountered while compiling SDXL. I've had a report that this issue still occurs, I'll look into it at some point, it may require setrecursionlimit somewhere else, and the issue can be bypassed by commenting out fuse_group_layernorm_ops or the entire fuse_group_ops
