Compilation crashes if a `title` prop starts with a number

[erunion]

const { compile } = require('.');

const schema = {
  "title": "2022 Example Schema",
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "example": "61e36b8fc12c4d8fd0842f76"
    }
  }
};

compile(schema).then(ts => console.log);

I can fix this by removing proceeding numbers from title and name props in the schemas I'm supplying but it'd be nice if the library was able to detect this and strip them themselves so any interface or type name it generates is valid.

I'm working on this.
