Rewrite log storage, remove server/ and deflate (#19)

* Rewrite log storage, remove `server/` and deflate

- Rewrote log storage to be single file and bucket-friendly
- Removed `server/` as it's outdated and unused
- Removed deflate as compression will be performed externally

* Fix some fuzzer things on Windows

* Add more information to saved logs

* add back file stuff
