fix error with float32 error with json.dumps in server mode

[Aprilistic]

Hi there!

I found that when I use langid in server mode langid -s, and send a request curl -d "q=This is a test" localhost:9008/detect I get an error with json.dumps because of its compatibility with float32.

This error also happens with the original langid code but the repo hasn't been updated for a while.

So, I added a custom encoder to prevent the error, which works well now.
You can find how I changed it in this commit log.
