Possibility of pixel-centering the pointings #504

Description

I was wondering whether it would make sense to add a function that forces the pointings at the centers of the pixels for a given nside. This could be useful to ensure that the pixels used when scanning are exactly the same as the ones used at the map-making step.

I discussed this with @paganol last week, and he suggested introducing a new function, at the same level as precompute_pointings, that centers the pointings and reassigns them accordingly.
