Outdated peer dependency with Typeorm

[SishaarRao]

TypeORM is now on version 0.3.11. Due to this library's peer dependency, this means that the package is no longer compatible with the latest version of TypeORM.

We should upgrade the TypeORM dependency and make any fixes if necessary.

@gboston Happy to make a pull request for this, however I'm unable to push my branch to the repository.

Only change needed to be made is to change the package.json file to the following. Looks like no tests needed to be updated, at least when I did this locally

{
  "name": "fastify-typeorm-plugin",
  "version": "3.0.0",
  "description": "Fastify plugin for typeorm",
  "main": "index.js",
  "scripts": {
    "lint": "standard | snazzy",

  },

    "standard": "^16.0.3",
    "tap": "^15.0.9"
  }
}

Note the changed lines

  "version": "3.0.0",

and

  "peerDependencies": {
    "typeorm": "^0.3.11"
  },

After merging the PR, the new major version would need to be published as well
