Add option to exclude certain dependencies and their trees

[beeequeue]

If you use ESLint you are almost guaranteed to have multiple versions of the various dependencies pulled in by the ancient and untouched @eslint/eslintrc package

Being able to exclude @eslint/eslintrc>* from duplicated dependencies would help a lot here

that makes sense to me 👍

currently we don't parse the tree, we have a flat list of all packages. so we can't easily figure out the hierarchy

if we parsed lock files fully we'd need to introduce yaml for example (the parser)

maybe we can initially just have a regex or exact match with the current architecture
