Allow transform full JSONSchema to typescript, instead on single type

[linonetwo]

Hi, I used to use json-schema-to-typescript, but it has some problem transform large JSONSchema bcherny/json-schema-to-typescript#404

I hope I can use quicktype-core to achieve a similar thing:

// json schema file names as input
void jsonSchemaFilePaths.map(
  async (fileName) => await quicktypeJSONSchema('typescript', fs.readFileSync(fileName)).then((tsContent) => fs.writeFileSync(fileName.replace('.json', '.ts'), tsContent)),
);

But quicktypeJSONSchema in the example ask me to add a type name as input, which makes things difficult, because I have to scan the JSON Schema file to collect all the type names, while quicktype's cli seem to automatically transform full JSONSchema to typescript, instead of on a single type.

So how to programmatically do transform, and make it as simple as using cli: just put in input file name, and output file name?
