reuse large downloads AMAP

[sergpolly]

there are a few big files being downloaded by different notebooks - and sometimes they are forced to go to different folders - e.g. hg38 fasta file to ./ or ./data/ (compartments notebook vs CLI notebook) - this is clearly redundant and should be aligned for better reuse

I'm not forcing any updates because not sure if ./ is better ./data or other way around ... imho ./data is slightly cleaner...

I think we discussed that they should go to ./data, but not all of the notebooks have been updated
