Has this cell type annotation worked?

Present dataset is the result of applying reference-based RCTD cell typing method on the 8um bin of the public P2 human CRC dataset as downloaded from 10x website. Public single-cell HTAN CRC data (validation cohort) from CellXGene was used as a reference to assign cell labels. The choice of CRC for this illustration is purely random. The dataset structure is as folows: Interested parties are invited to look at `squidpy/visium-hd-crc-p2/squidpy.h5ad`, it contains the original counts matrix in `adata.X`, associated spatial information, as well as most abundant cell type in `adata.obs['cell_type']` and raw RCTD outputs in `adata.uns['cell_types']`. Furthermore, `example.ipynb` contains some toy scripts to get started with analysis. Other files are untransformed and transformed versions of source data and some basic squidpy plots.
