Add option to ignore 'unused' dependencies in configuration file.

[InstantlyMoist]

Describe the feature

Hi,

When using mongoose together with Nuxt 3/nitro you often run into the issue that your models are tree-shaken out of your final build. Leading to 500 errors because a reference could not be found to this file.

Solving it like this:

    const _ = [
        IModelA.length,
        IModelB.length,
        IModelC.length
    ]

works, but I think there has to be a cleaner solution. I'm proposing some kind of option file to allow for certain directories and/or files to be ignored from the tree-shaking logic.

Maybe like this:

nitro: {
    dontShake: [
        './models/**'
        './important_file.ts'
    ]
}

Additional information

• Would you be willing to help implement this feature?

Yes, but someone would have to give me a starting point, as I'm not familair with the internals of nitro.
