* Removes all usage of block_on, and use a oneshot channel instead. Calling `block_on` panics in certain context. For instance, it panics when it is called in a the context of another call to block. Using it in tantivy is unnecessary. We replace it by a thin wrapper around a oneshot channel that supports both async/sync. * Removing needless uses of async in the API.
