Printing the latest RapidWright version number

[harnhua]

Hi,

I just wanted to share a tip from the RapidWright team which helped when I was debugging a problem.

Ensure you are running the latest version of RapidWright (2021.2.0 as of this writing).
One way to quickly check is to add this line to the beginning of your RapidWright program:
System.out.println(Device.RAPIDWRIGHT_VERSION);

Thank you, Chris, Eddie!

Cheers,
