Maximum recursion depth exceeded when `resolving schedule from trace`

[Oh-Afterglow]

When simulating a design with all rewind keyword removed (#8), LightningSim throws a RecursionError before which a part of call stack (marked in the error message below) repeats 142 times:

RecursionError: maximum recursion depth exceeded

The design triggering the error is a 4x4 systolic array similar to the one used in #8. Setting a larger max recursion depth does not prevent the error from being thrown.
