folder_compare
=========================
A library to recursively compare files in two folders and return two lists of files: One with new files and one with changed files.
`folder_compare` also takes a list of Strings acting as exclude patterns using `RegexSet`.
Overall the functionality is comparable to a `diff -rq folder1 folder2 -X excludepatterns.pat` on unix like systems
For recognizing changed files, hashing with [`FxHasher`] is used.

```
use walkdir::WalkDir;
use std::path::Path;

let excluded = vec![".doc", ".txt"];
let (changed_files, new_files) = folder_compare::compare(Path::new("/tmp/a"), Path::new("/tmp/b"), &excluded).unwrap();
```
