n_subap in pupdata and pyr_slopec

[guidoagapito]

n_subap in pupdata and in pyr_slopec is not coherent:

• in pyr_slopec --> self.n_subap = self._pupdata.ind_pup.shape[0]
• in pupdata --> return self._ind_pup.shape[1] // 4

I think that in pupdata it should be

return self._ind_pup.size() / 4

or

return self._ind_pup.shape[0]

so it will be coherent with pyr_slopec. Then a lot of method of pupdata should change:

e.g.

self._ind_pup = self.xp.empty((4, 0), dtype=int)

should be

self._ind_pup = self.xp.empty((0, 4), dtype=int)

and

    def single_mask(self):
        f = self.xp.zeros(self._framesize, dtype=self.dtype)
        f[self._ind_pup[:, 0]] = 1
        return f

Just to report a couple of examples.
