Add yarn support

[vikumDheemantha]

The current version is not working with yarn and even windows installing command with escape character is not working (But it can be installed through the first command). It would be great if you enhance this to support yarn install since create-react-app uses yarn as the default package manager.

I successfully installed it with yarn on windows today by putting the package name in quotes in powershell:
yarn add "@david.kucsai/react-pdf-table"
