Rustic cleanups, dedups and making the code less hard to read in general (#251)

* typos :help_me:

* (part 1/?) massive cleanup to make the code more Rust-ic and cut down heap allocations.

* (part 2/?) massive cleanup to make the code more Rust-ic and cut down heap allocations.

* (part 3/?) cut down some pretty major heap allocations here - more Bytes and BytesMuts, less Vec<u8>s

also I don't really understand why you need to `to_vec` when you don't really use it again afterwards

* (part 4/?) deduplicate error handling in backblaze logic

* (part 5/?) fixes, cleanups, refactors, and reformatting

* (part 6/?) cleanups and refactors

* remove loads of `as_str` in types that already are `Display`

* Revert "remove loads of `as_str` in types that already are `Display`"

This reverts commit 4f974310cfb167ceba03001d81388db4f0fbb509.

* reformat and move routes util to the util module

* use streams

* Run prepare + formatting issues
