savefile arg support and fixed blank google vision pages #20

Fixed issue where google vision returns no data back for blank pages which then caused gcv2hocr to crash (fixes #19)
Added support for argument --savefile where if defined will output to file instead of console (fixes issue for me in windows cause I am compiling these tools to exe)

The readme will need to be updated to document the new --savefile argument. I didn't update the readme because I didn't know if you wanted to first move this change to the C version. This change helped me on windows because I had to parse the console output and write to file in my code whereas this simple argument just handles it for me (that way I don't have to worry about accidentally writing errors to a file or something because windows didn't detect the program crashed correctly).
