Add a command line tool

[jkomoros]

• Allow selecting a different seed to execute as a parameter
• Command should print help
• Don't require -- in the command
• A way to load a seed from a specific file
• For ids that are ambiguous (in multiple packets), ask using a choice UI in CLI first.
• Private seeds should not be shown unless --all is passed
• Add a list command that prints out all seeds
• Use inquirer live menu to select a seed to print
• Allow passing overrive key/value pairs to set in environment
• diagram includePrivate
• include description in list.
• A tool to print all expanded seeds (to diagnose unrolling issues)
• a --mock command to set the environment to mock
• Add a command to list all named let/let-multi properties in a packet (or rooted from a seed). This will help find typos.
  • Generally a analyze command that prints out var/lets (showing ones that are mismatched), store key values and namespaces, memory namespaces, whether there's a dynamic reference, and any remote seeds it references
• Allow --packet to pass multiple packets. Everywhere it's used (e.g. garden.diagram), have the treatment of an empty array
