Add an experimental layout command

[sz-piotr]

This PR adds a layout command. This command downloads sources from Etherscan and compiles them with solc to get the storage layout. Then it removes indirection and recursion from the layout, flattens the layout and finally combines it with the layouts of other implementations to get a unified view of the storage.

This is experimental functionality. While there are tests some edge cases surely exist. There is also the issue of compiler versions. Currently the installed version of solc is used, but that should be changed to a dynamic version based on the sources.

Try it with the following command for the zkSync diamond:

lgtm, just one suggestion

What do you think about making this function return the results (the layout variable) and the function above can save them. This would allow us to later export this runLayout and use the results without having to interface with the filesystem
