Embedded executables do not run

[rjdbcm]

Describe the bug
As far as I can tell this is from a known limitation of Cython. When you import from Aspidites.tests.examples.compiled without invoking main it just grabs the current stack frame from the calling scope. As of now Cython does not make use of stack frames and disposes of them as soon as you are out of scope.

$ ./compiled
Traceback (most recent call last):
  File "Aspidites/tests/examples/compiled.pyx", line 79, in init Aspidites.tests.examples.compiled
    C = pmap({'a': (3+5), 'b': 8, 'c': True, 4: None, 'd': Maybe(SafeExp, 6, 2*5+3)})
  File "Aspidites/monads.pyx", line 37, in Aspidites.monads.Maybe.__init__
  File "/Users/ross/.pyenv/versions/3.9.6/lib/python3.9/inspect.py", line 1552, in stack
    return getouterframes(sys._getframe(1), context)
ValueError: call stack is not deep enough

To Reproduce
Steps to reproduce the behavior:

1. Run the binary generated from embed.

Expected behavior
It should print hello world

• OS: macos-11
• Version 0.14.31

Proposed Workaround
I tried getting rid of stack inspection but the first call to Maybe or SafeExp but seemingly got the exact same error. Not sure if that's due to caching from Cython or what...
