Feat(arbiter-engine): config based simulation workflows

[kinrezC]

Give an overview of the tasks completed

• Allows users the ability to control their simulation workflow via modifying a configuration toml file once the appropriate behaviors are implemented.
• Introduces two example tests showcasing what the config driven simulations might look like. See the examples directory.
• Introduces the arbiter-macros crate. This crate effectively replaces the deprecated arbiter-derive. Currently contains one derive procedural macro that expands an enum into composable agent behaviors. The behaviors are injected into the World::build_with_config method where they are attached to the appropriate agents.

Link to issue(s) that this PR closes
Closes #825 and #728

love to see this. Why are there duplicate behaviors in the toml?
