Add state dump to compare Native and VM

[JulianGCalderon]

This PR adds a new feature state_dump that dumps transaction execution info to a file, so that we can compare Native with VM for correctness.

It also adds scripts for analyzing the dumped information.

It looks very nice overall!

Maybe the only thing it would be nice check is that right now the state_dumps folder is created relative to the path where the command was performed. Is it possible to have an absolute path? if not, there will be a new states-dump folder every time the command is run somewhere where there's not such folder.
Perhaps it's just me, but I can run the command being in the states-dump folder and have the mentioned result.

There might be a way to have it set to an absolute path relative to the repository (by traversing the directory structure until you find a Cargo.toml, for example), but I don't see a reason to do it. By doing that, you eliminate the possibility to compile the binary and run it elsewhere. I think the current behavior is more intuitive.
