bdk-ffi Create Transaction from hex

Describe the enhancement

Types like Transaction can create new Transactions by passing in transaction bytes. It will be helpful to also create transactions by passing in the string hex of a transaction.

Use case

Create a transaction from a transaction hex.

Additional context

@rustaceanrob hashlike types has useful methods that types like Transaction can benefit from. Like from_string. Could this be a method we add directly to Transaction impl?

This would mirror the PSBT API. I don't see any problem with adding this.

cool it was just as easy for me to write that function in a PR as it was to comment so I figured id just do the PR (especially since the from_string stuff was fresh in my mind from a recent PR of mine). I'll let CI tests pass then add you as a reviewer
