Add `try_vector` macro for initialization of a `Vector` with fallible data collection types

[chrissimpkins]

This approach will take a single data collection argument type that is supported by the Vector TryFrom trait implementations. These are data collection types that may not have known length at compile time.

The approach with a std lib Vec type will be:

let stdlib_vec = vec![1, 2, 3];
let v: Vector<i32, 3> = try_vector!(stdlib_vec).unwrap();

The macro will return an error when the std lib Vec length differs from the requested Vector length:

let stdlib_vec = vec![1, 2, 3, 4, 5];

// expected length 3, received length 5
let res: Result<Vector<i32, 3>, _> = try_vector!(stdlib_vec);

assert!(res.is_err());
