"Statistics with Rust" book ch. 2 issues

[Marius Ileana]

Hey there!

For now, I found two issues found on chapter 2:

1. statis crate does not exist anymore.
2. SalaryRecord must have company_size: String instead of i32), according to the dataset.

These beg the question: is there a place for an Eratta of the book ❔

Thanks!
