Native SC.MEB

• I created a default config, but there aren't really any parameters that they modify, so I only included n_pcs and n_genes.

• The method only works for Visium and ST, it seems, but I made it such that it defaults to ST if the technology is something else, just to let it give it a go.

Closes #278

Looks good!

Though given their find_neighbor function, I would say it doesn't make sense to apply this method to imaging-based datasets. If we have time (and energy), we can make a specific offset case for each type of NGS-based technologies (SlideSeq, Visium HD, StereoSeq, ST and Visium).

This also applies to BayesSpace and GraphST. Maybe we can create an issue on this matter and move on to merge this PR.

Good idea. Alternatively, we can find a better neighborhood function. In any case, this method hasn't had a github update in 3 years, so it probably isn't worth spending too much time on.

Agree...Also if we find a better neighborhood function, it will come back to the question of whether this is still the same method. I think it's important to keep the "native-ness" of the methods implemented.
