HNOCA fixes oregano

[aregano]

I tried to run HNOCA and it failed to initialize. Some simple fixes sorted it for me.

1. Get rid of the check_deps() functions, as sometimes they fail to actually detect the packages they have been assigned (and besides the pipeline would fail regardless and the terminal will notify you which package is missing)
2. fix wknn arguments allowing for gpu usage
3. Change order of how the best score is found before the best label so the .max() function does not encounter a string that would throw an error

Furthermore there are some other fixes in the scpoly package that I have also modified so the mapping can work properly.

Thanks for providing us with these nice packages! I thought it was a pity that I could not get them work first for a few tiny issues :)
