TEI export

[eroux]

84000 needs an export in TEI for import. There used to be an export on the previous derge-kangyur repos:

https://github.com/Esukhia/derge-kangyur/blob/master/scripts/toTei.py

it should be adjusted to the opf format and integrated here

Thanks Elie! As soon as we know if @domlatham has added features specific for 84000 we'll be good to go

Great, thanks. We used the toTei.py script unedited, except for the paths/filenames.
