File total tokens added to report output

[jazerix]

This PR adds the count of tokens in each file such that you get an idea of how much of each file is covered by a match. This is especially nice if you are not using the report viewing but ingesting the files in other ways.

Alternatively, this metric can also be converted to a similarity using the same formula found in JPlagComparison.java

I'm aware that it doesn't give you the complete picture, but having a sense of perspective on each file is nice.

Let me know what you think 😃

That is a good idea; I will have a look at it.

@jazerix could you run mvn spotless:apply to fix your formatting?

[jazerix]

@tsaglam Certainly! I've also renamed the two new variables to align with the current naming scheme.

One minor suggestion

@TwoOfTwelve could you take a look at this PR? Resolve the conflict and maybe even test if it affects the performance if we run it for a large dataset?

[TwoOfTwelve]

The code looks good to me.

I measured the runtime of the entire application using a bunch of data. Without the changes it took 0.91012 seconds on average, with the changes 0.91279 seconds.
I don't think, this will have a noticeable impact on the performance.
