Better error & retries

In this release we rethinked how we return errors to fix some bugs and allow them be more useful on the Crush side.

In the process, we also fixed an issue with retries running more time than it should, due to Fantasy having it's retry mechanism on top of the SDKs retry. We disabled the SDK retries and kept ours.

All this is an ongoing work, and you should expect more improvements in this area soon.
