unable to reuse configuration object

[ferrao]

If i create a config object like this:

var config = {
    size: '10M',
    interval: '30s',
    rotate: 5
};

and reuse it on two calls to rotating-file-stream, the second call will fail with:

Error: Don't know how to handle 'options.size' type: number

The type number seems to come from expanding the original object from 10M to 10485760.

My workaround is to create a new object with exact same properties on each call to rotating-file-stream, but in my opinion, it should be up to the module to clone it and not impose this non documented restriction on the user.

Yes it's true, the module destroys tho options object in input.

Going to fix this; in the mean while please use two different equivalent objects.
