@types packages causing false positives

[sgen]

As of TypeScript 2.0 type definitions of pre-existing packages are available via @types/pkg.

depcheck should be able to recognize this.

Simply noting the packages that being with @types/ and checking them against a list of used packages with the corresponding package name should do it.

Output of depcheck --json:

{
  "dependencies":[

  ],
  "devDependencies":[
    "@types/jasmine",
    "@types/jquery",
    "jasmine",
    "karma-chrome-launcher",
    "karma-jasmine",
    "karma-typescript"
  ],
  "missing":{

Hey @sgen thanks for the issue, would you want to make a PR for this?

[sgen]

I might, very busy atm so I can make no promises.

This seems to be a duplicate of #163.

Closing as duplicate of #163 -- we'll get this in for the 1.0 release
