Remove dependency on node-hid

[pgebheim]

Can we use dependency injection to pass in one of the transports from the new ledgerjs libs?

https://www.npmjs.com/package/@ledgerhq/hw-transport-hid

This would mean that deps that only need browser wouldn't need to deal with node-hid dependency which is a pain in many ways including limiting node10 support.

I believe those packages are for the new ledgerjs library, but we are on the legacy ledgerco library. Also, requiring the user to dependency inject adds complication to library configuration and thus increases support burden.

That being said, I do hate native module dependencies, especially when they aren't actually needed for your use case. Going to leave this open for now and decide later whether to do it or not.
