Allow search by multiple options of one type in one call

It would be great to be able to pass an array of possible values to match and get all the results back at once. I realize that it is possible to do them one at a time, but this seems like it could be more performant if the library handles it.

for instance: find('pid', [1234. 2345]);

This could return 0-2 results.

For ports, you would likely need to include this #33 so that we can tell which ones matched.

Sorry I don't have plan to support this feature so far as it was designed to find single process.

I will merge your PR if it's well designed~
