Notes for reviewer - perhaps @leoporoli ?

1. src/el & src/cl & src/node_metrics_info & src/participant.star &
src/participant_network.star & src/prelaunch_data_generator/ &
src/snooper & static_files have just been lifted and shifted
2. constants is just a union of the two
3. ⚠️ parse input is a best effort union of the two; needs some 👀 
4. shared_utils.star is a best effort union of the two
5. package_io, shared_utils etc used to be at root level they have been
shifted
6. eth-network-package has been changed to eth2-package throughout all
`.star` files

Pending after PR - perhaps @leeederek ?
1. Get the README's to make sense together
2. Get the run.gif over here?

⚠️  Note to testers

1. Clone the package
2. Check out this PR
3. Run `kurtosis run .` with args of choice
