Possibly reduce crate size

[darnuria]

PR: #203

I ran cargo diet --dry-run(cargo diet project) on this crate and seems like it's possible to improve the size of the crate.

By default test are incorporated in the final crate and it can size up significantly the final crate. The rational about that? Not everybody in the world have top notch internet acces or a huge amount of space on the disk.

If it's okay, I can do a pull-request about it.

Hmm, I didn't realize that these test files were being included in the final crate. I was under the impression that the Rust test files (e.g. src/tests/mod.rs) wouldn't be included due to them being annotated with #[cfg(test)], and I certainly didn't realize that the non-Rust files would be included as well. We'd definitely be willing to accept a pull request to fix this!

#203 is merged, maybe it's time to close this issue if exclusion of the test in the package is enough.

[patrickfreed]

Yep, I think we can close this. Thanks again @darnuria!
