hips2fits: fast generation of FITS cutouts from HiPS image datasets

We present hips2fits, a new service generating FITS images cutouts from HiPS (Hierarchical Progressive Surveys) tiles.
The code base is powered by Astropy and Rust (wrapped in cdshealpix-python library) and uses Numba to speed up the process. The generation time scales linearly with the number of pixels of the requested cutout and reaches 1 million pixel per second.
The service takes advantage of the huge collection of more than 500 image HiPS available at CDS and at other HiPS nodes.
The Web API is exposed by the Falcon framework.
