FIX: Boolean casting comparison should be in real domain

[SwayamInSync]

closes #41
Find one more issue in scalar implementation as from cpython the signature of quad_nonzero functuon should be

typedef int (*inquiry)(PyObject *);

and earlier we were returning a PyObject (which is bad as everything might turn up True). This is also fixed here

@melissawm was there any env variable ACTIONS_ID_TOKEN_REQUEST_URL for docs?

[SwayamInSync]

docs are successfully got hosted here https://numpy.org/numpy-quaddtype/
but in PR it is asking for some missing env variable

[ngoldbaum]

I think if you want to have a docs preview in PRs you'll need to separately configure that.

[ngoldbaum]

Many doc build actions workflows skip the deploy step on PRs

[SwayamInSync]

In that case please feel free to review the PRs and we can merge if they sound good.
I'll see how we can configure the action for PR separately

LGTM, thanks for the fix!
