Similar to BitBoxSwiss/bitbox02-api-go#141

I'm going to need some instructions on how to test this PR :)

Hmm you didn't test the same PR in Go 😄 BitBoxSwiss/bitbox02-api-go#141

There is a simulator test and unit tests here, isn't that sufficient? I could try to provide a new file in examples/, but it's not so great to keep adding more examples there 🤔

@NickeZ added an example anyway, run make example-btc-sign-op-return, see added commit.
