Differential observers (#868)
* reduce diffexecutor constraints for new (so it may be used in a manager-less environment)

* add differential observers

* finish differential observeration

* requirement for observers (weak), default impl for time observer

* make the map swapper, revisit how differentialobserver is implemented

* semi-specialise multimap, add example

* improve example slightly

* fix clippy lints

* fix last clippy issue

* better docs + example flow

* improve example: correct map sizing + multimap vs split slice

* correct some comments

# Baby fuzzer (swap differential)
This is a minimalistic example about how to create a libafl-based differential fuzzer which swaps out the AFL map during
execution so that both maps may be measured.
It runs on a single core until an input is discovered which both inputs accept.
The tested programs are provided in `first.c` and `second.c`.
You may execute this fuzzer with `cargo make run`. If you prefer to do so manually, you may also simply use
`cargo build --release --bin libafl_cc` followed by `cargo run --release --bin fuzzer_sd`
