Fix numba 0.61 compatibility

[ricardoV94]

Did not see any change in performance running the existing benchmark tests on my machine

The __mm_cheap option was moved elsewhere in numba/numba@a5e2195

If anybody sees differences in performance it seems like the new internal API is controlled by setting _loopvect and _opt_level private attributes, so we could patch those, depending on the installed numba version (not very keen on this)

I'm fine with just deleting those, they were a bit scary even if we ignore the version problems.

Thanks for jumping on this so quickly @ricardoV94
