Change data storage to files

[laraujo7]

I've added:

• USAGE.md docs if applicable
• CHANGELOG.md

@vbrazo So, I wondered if we could move the data passed in the functions to a file, which would improve the reading of the modules.
This was my attempt, but I didn't know which type of file to use, so I left it as a txt. Do you think a yml or a json file would be better?

I would be down to change everything if it gets accepted 👍.

Could you please provide benchmarks to show if this approach is faster than the current one?

I'd also like to get an opinion from @igas or @anthonator on this PR.

So, I made some changes after running the benchmark as I found out that my solution was a bit slower. After my optimization, this was the result.

What do you think @vbrazo ?

@laraujo7 thanks for adding the benchmark.
