`no-commonjs` does not appear to work for TypeScript

I have the following rule enabled:
```js
// disallow require()
// https://github.com/benmosher/eslint-plugin-import/blob/master/docs/rules/no-commonjs.md
'import/no-commonjs': 'error',
```

However, in my TypeScript source file, the following line that I expected to error does not:
```ts
import Boom = require('boom')
```

Should it?

Start with the no-commonjs rule documentation linked in the issue and reproduce the reported TypeScript example, `import Boom = require('boom')`. Trace how the rule handles TypeScript syntax and identify the relevant rule tests or parser behavior. Done means the expected handling is established and covered by an appropriate regression test or documentation update.
