Initial code dump: matrix feedbot, aka bender

This is a rewrite of our old feedbot in rust, heavily inspired from
rek2's INN matrix bot and making use of some bits from matrix-rust-sdk

This is an asynchronous tokio-based matrix client using a stateless feed
fetcher implementation based on reqwest, it uses feed_rs for parsing RSS
and Atom feeds. State persistence is achieved using a simple file-backed
datastore with serde_yaml as a serialization format.
