Update to bdk 0.17.0

[notmandatory]

Description

Fixes #81

Notes to the reviewers

Also added verify feature flag which enables transaction verification against consensus rules during sync.

I also had to disable the reserves tests and that feature will be broken until we can get it updated to use bdk 0.17 also. I created an issue https://github.com/weareseba/bdk-reserves/issues/4.
