Clarification on use of idb crate.

[devashishdxt]

Hi @fl0rek. I was looking at the usage of idb crate in blockstore and noticed that you added direct dependency of idb crate just for error conversion here. Is the something specific to this project or rexie unintentionally exposes an API that returns idb::Error?

@devashishdxt actually I remembered what it was initially.
KeyRange error types are idb errors not wrapped in rexie::Error::IdbError, so it's a bit of a leak indeed.
