Interpolate healpix maps #784

Closed keskitalo closed 1 month ago

keskitalo commented 2 months ago

Add an operator that uses bilinear interpolation to generate continuous scanned signal from a HEALPix map. The maps are stored in node shared memory to reduce the required memory.

When scanning and co-adding multiple maps, they may be of different resolutions and some or all interpolated maps may be unpolarized.
