Infinity

I think using the string "Infinity" could become a bit inconvenient. What do you think about using -1 instead of "Infinity"?

Naming

I actually really like the description you made for the configs :-)

Here are some thoughts about the naming of the configs:

• Using the word "import" instead of "traversal" could make the meaning more clear because "depth" already indicates some kind of traversal.
• The word "depth" should be included
• The word "max" could be useful to indicate that this is the maximum allowed depth to traverse.
• Typescript has a configuration called maxNodeModuleJsDepth: The maximum dependency depth to search under node_modules and load JavaScript files.
• ESLint has a configuration called max-depth: Enforce a maximum depth that blocks can be nested

Here are some suggestions (unordered list) of what it could be called. What do you think?

• maxExternalImportDepth & maxInternalImportDepth
• maxExternalDependencyDepth & maxInternalDependencyDepth
• maxNodeModuleImportDepth & maxProjectImportDepth
• moduleImportDepthInternal & moduleImportDepthExternal

Documentation

When you add documentation you will need to:

1. Edit ./docs/readme/config-table.md
2. npm run readme
3. npm run prettier:write

Thanks for the feedback!

Using -1 instead of "Infinity" is definitely a nicer way, I will change that soon!

For the names of the configs i found maxNodeModuleImportDepth & maxProjectImportDepth to be my favourite.
I think that "NodeModule" and "Project" are a bit more intuitive than "internal" and "external".

I also like them. Let's go with those two then!

It looks great now, - I'll merge this in a couple of hours!
