Better graph output

[fe3dback]

Some possible graph improvements:

1. Draw nodes from commonComponents and commonVendors with different arrow style (like "uses" instead of "arrows"), maybe always in right/left side of graph and with different color.
2. Dont draw nodes with anyComponentDepsandanyVendorDeps` (it DI container)
3. Replace d2 styles with classes
4. Instead of random colors - we can use golang brand colors
5. max-depth flag (useful with --focus option). Draw only first X depth levels of graph (counting from first node)
