Current crate name

This library provides, current_crate_name(), a const function that returns the name of the current crate.

Most other libraries that provide this functionality rely on a macro and\or the CARGO_PKG_NAME environment variable. This library relies on the built-in module_path!() macro instead to provide a simple const fn that achieves the same result.

Usage

```rust use currentcratename::currentcratename;

asserteq!(currentcratename(), "currentcrate_name"); ```
