Minimal opinionated resource embedding
Files are loaded relative to the Cargo.toml file
```rust use embeddy::Embedded;
/// Contains all the files stored in the "test" folder
/// use the [Embedded::get
] method to access the folders
struct MyResources;
fn main() { let file: Option<&'static [u8]> = MyResources::get("test.txt"); let nested_file: Option<&'static [u8]> = MyResources::get("sub/test.txt"); } ```
