updated dependencies and fixed stuff - replace serde_derive by feature of serde incl. source code modifications to compile - reduce futures-timer to "2.0" to be same as async_std - update notify - removed mio, bincode and lz4 compress in common as networking is now in own crate btw there is a better lz4 compress crate, which is newer than 2017 - update prometheus to 0.9 - can't update uvth yet due to usues - hashbrown to 7.2 to only need a single version - libsqlite3 update - image didn't change as there is a problem with `image 0.23` - switch old directories with newer directories-next - no num upgrade as we still depend on num 0.2 anyways - rodio and cpal upgrade - const-tewaker update - dispatch (untested) update - git2 update - iterations update 2020-07-06 14:23:08 +00:00			`use serde::{Deserialize, Serialize};`
