Wrong module name in typescript type info

[theronfff]

Environment details

• OS: linux
• node-pty version: 0.7.6

Issue description

If using node-pty-prebuilt in a typescript app I get the following error from tsc:

 error TS2306: File '.../node_modules/node-pty-prebuilt/typings/node-pty.d.ts' is not a module.

7 import * as pty from "node-pty-prebuilt";
                       ~~~~~~~~~~~~~~~~~~~

The fix is to modify node-pty.d.ts from this:

declare module 'node-pty' {

to:

declare module 'node-pty-prebuilt' {
