Static imports for $refs about json-schema-to-typescript

[codan84]

To go around the issue I had to introduce a kind of root-schema to hold all assets.
root.json :

{
  "id": "Root",
  "title": "Root",
  "description": "Root schema for all assets",
  "type": "object",
  "allOf": [
    {
      "$ref": "schema/new-draft.json"
    },
    {
      "$ref": "schema/draft.json"
    },
    (.......)
  ]
}

Each of the ones referenced in the above then references other schemas.
Having this I can run:

npx json2ts --no-additionalProperties --no-enableConstEnums -i 'schema/root.json' -o packages/model/src/generated-types.ts

To get something like:

/**
 * Root schema for all assets
 */
export type Root = NewDraft & Draft & (...);

/**
 * A new draft
 */
export interface NewDraft {
(...)

export interface Draft {
(...)

export interface (...)

I do not like that export of Root, but can't figure out a way to get the desired outcome any other way...
