code duplication from ledger-oasis repo

[pro-wh]

Looking at source code in files in src/ in this repo and source code in files in js/src/ in Ledger Oasis app repo, there is a lot of copying/duplication.
What would be the best way to avoid that?

I didn't know about there being a copy of this module in the repo of the app itself. Is this intended? How did the two copies com to be?

I also don't know the genesis of this 🙂.

Can you open an issue in this repo to track this unusual code duplication and we can tackle that separately from this PR?
