v3.0.0 Power Spectrum Estimator

This release contains the new optimal_mapping_radec_grid.py file which contains a new SkyPx class that handles the pixelization on ra/dec grids. The script naturally maps the visibilities to the defined radec pixels.

Also included in this release is the image_cube_compilation.py, which reads in the map files from different frequency channels, converts them into mK, and compile them into an image cube.

Another script is called dom_pspec.py takes the image cube and calculates the power spectrum. Currently, the power spectrum estimator is just FFT, with some tapering function along the line-of-sight.

v1.0.0

The first released version accompanying the direct optimal mapping publication (Xu et al. 2022 https://arxiv.org/abs/2204.06021)
