enable asserts in fuzz target VMs
Added mutators to merge two existing seeds
Stack 1-3 changes rather than only doing 1 mutation.
Simplifier improvements: bugfixes, faster fixed-point search.
Fixed issue treating failures as executions (printing . & double counting)
New simplifier constraint "contains output"
Better error when port is already taken and observatory fails to start
Auto-snapshot scripts for users
Better error when script is erroneous (though erroneous snapshots may not give a good error message)
switch from vm_service_lib to vm_service
Coverage stats by path as well as files that have not been executed.

Run manual seeds first, corpus seeds second, seed dir third, for better performance when the seed dir requires minimization.

Specifiable fuzz count limit, and exits 1 if any failures detected.
Time printouts during simplification
Warning if simplifier changed output / "same output" constraint no longer defaults to ON.
Run the simplifier to a fixed point when called from CLI.
Optimized optimizer for long input sequences.

Automatic simplification of seeds
Better simplification algorithm
Optimized profile collection. crash_on_bad.dart now runs 6x faster, though programs which do more meaningful work will see less gain.
Optimized simplifier. Will not collect coverage unless necessary.
