aleo-std-storage

This crate uses aleo-std-storage to implement convenience methods for accessing resources in Aleo storage.

```rust use aleo_std::prelude::*;

fn foo() { // Prints the Aleo directory. println!("{:?} exists: {:?}", aleodir(), aleodir().exists()); // Prints the Aleo ledger directory in production mode. println!("{:?} exists: {:?}", aleoledgerdir(2, None), aleoledgerdir(2, None).exists()); // Prints the Aleo operator directory in production mode. println!("{:?} exists: {:?}", aleooperatordir(2, None), aleooperatordir(2, None).exists()); // Prints the Aleo prover directory in production mode. println!("{:?} exists: {:?}", aleoproverdir(2, None), aleoproverdir(2, None).exists()); } ```
