* Add placeholder client for implementing coconut interactions

* Add db for persistance

* Add nymd client

* Add new coconut-bandwidth contract

* Call deposit function

* Introduce error handling

* Call the old flow of getting a signature

* List available tx hashes

* Add signed req in body

* Save signature received

* Add event generation

* Checks in validator-api

* Fail with error instead of panic in validator-api route

* Fix contract address and small bug

* Add file db for storing previous signatures

* Encrypt and store data in validator-api

* Decrypt the received signature

* Remove tx hashes after getting credentials

* Small listing changes in client

* Change response so that it easier to serialize

* Error message is sent to client for display

* Remove already signed error and return the previous sig

* Merge signature with deposit data in client

* Entrypoint for getting the encrypted signature

* Refactor blinding stuff so that it can be backed up

* Backed up the blind sign request

* Client can re-request the encrypted signature shares

* Update crypto features

* Fix clippy

* Activate instantiate test and remove unused code

* Add tx tests

* Add verification key endpoint test

* Voucher consistency test

* Test for some errors and a race condition on blind signing

* Refactor and add client trait for enabling better testing env

* Test some more of blind sign

* Finished testing all extract_encryption_key paths

* Split into function test and endpoint test

* Test for correct signature

* Test for state functions

* Remove print

* Test blind_sign endpoint

* Test for cached signature endpoint

* Stricter types in voucher

* Rename signature with partial_bandwidth_credential

* Extra route levels

* Length check and remove some unused code from coconut interface

* Renamed coconut-bandwidth common crate

* Renamed verification_key to identity_key

* Use const instead of hardcoded values

* Use type aliases for crypto algorithms

* Remove unused mods, until needed

* Remove unneeded unwrap

* Fix some coconut issues that were blocking the wasm client build

* Move from sled to existing sql database
