Export noPlaceholders global variable in react-sizeme.d.ts

[jwoe]

Thanks for your work providing this component! I am using it successfully in a TypeScript project.

For testing purposes, we disable the placeholder mechanism as described in https://github.com/ctrlplusb/react-sizeme#server-side-rendering in our jest setupTests.ts file. As the global variable is not defined in react-sizeme.d.ts, the TypeScript compiler complains and we temporarily silenced it by adding // @ts-ignore. This PR should fix this issue for good and allow us to remove the ts-ignore.
