[doc] Help for tresequences users (msprime, slim) on how to save into DNADNA format
I completed the doc, in the Alternative format section, to illustrate how to save tree sequences into our npz format. It's a small trick useful for the time being since we don't support yet this format. People who already have their simulation scripts will know what to do to get npz files.
In addition, I wrote a small notebook example that I put in dnadna/examples. Does it seem to be a good location?
The issue for this (and the new lines on the doc) is that it won't be checked automatically, I'm happy to write the full example on another documentation page, or to write it in a .py file and add a test in tests/ : I wasn't sure what was the best way. I feel notebooks are good for newcomers (although in this case jupyter is not in dnadna conda environnement so they might need to install jupyter and the ipykernel if they want to run the full notebook).
Screenshot of the doc:
This is implemented in branch flora/doc/ts-to-dnadna-fmt
