Format printing a string or array panics when > 2 characters

[vezenovm]

Aim

I want to be able to format print string and array values.

Run either of these tests:

#[test]
fn test_print_bytes()
{
    let label_f = [1, 2, 3];
    dep::std::println(f"{label_f}");  
}

or

#[test] 
fn test_print_bytes()
{
    let label_f = "123";
    dep::std::println(f"{label_f}");  
}

Expected Behavior

I was expecting to be able to print both the array and string as expected.

Bug

Instead we get a panic with:

The application panicked (crashed).
Message:  range end index 3 out of range for slice of length 2
Location: compiler/noirc_printable_type/src/lib.rs:135

To Reproduce

1. Copy the snippet in the issue
2. Run nargo test --show-output

Installation Method

Nargo Version

No response

Additional Context

This is labelled both compiler and nargo as our println is provided type information by the compiler but is implemented using the brillig foreign call functionality that is implemented in nargo.
