Fixed an error when creating a new P1Reader object with no parameters… #9

When using the example code from the README.md file, the following error occurs:

/root/p1/node_modules/p1-reader/main.js:15
    debug.setDebugMode(options.debug);
                              ^

TypeError: Cannot read property 'debug' of undefined
    at new P1Reader (/root/p1/node_modules/p1-reader/main.js:15:31)
    at Object.<anonymous> (/root/p1/app.js:2:16)
    at Module._compile (module.js:570:32)
    at Object.Module._extensions..js (module.js:579:10)
    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)

    at Module.runMain (module.js:604:10)
    at run (bootstrap_node.js:383:7)
    at startup (bootstrap_node.js:149:9)

If no parameter was provided to new P1Reader(), the options parameter is undefined, which will result in an error when trying to read options.debug, since debug isn't a property of undefined. Asserting that options is an object will prevent this error.
