single digit study IDs

[mtholder]

this is currently a mess due to changing code and aliasing covering up inconsistencies:
studyID ot_9 is in study/ot__9/ot_9/ot_9.json
studyID pg_09 is study 9 in phylografter and is in pg_09/pg_09/pg_09.json

this is not an emergency because the studyID's listed in the files, resolve.
But I should clean it up at some point. Probably no point in fixing the code that generated the mess (because we are passed single digit IDs in both the ot and pg namespaces), but better aliasing (in peyotl) and some git mv operations would make the system more transparent.

@mtholder: Is this bug restricted to code that imports from phylografter? Or could this become a problem again if introduce a third "namespaced" source for studies?

I'm sorry to say that this would bite us if we added a new namespace... (a hack would be to add 10 bogus studies in a new namespace so that it would not affect any real studies )

why not just start the counter at 10?
