[O] Babel results in other lang code

[Satoru KURASHIKI]

hi,

I've tried to write babel extension for typescript.
cf. https://github.com/lurdan/ob-typescript

Because "results: code" forces same language in results,
it outputs transpile results enclosed with #BEGIN_SRC js #END_SRC
assuming "results: raw".

I want it to do this with more sane way (not disturbing header parameters),
are there any nice tweaks?

regards,
