SessionID.init(rawValue:)(rawValue: String)
```

Creates a new instance with the specified raw value.

If there is no value of the type that corresponds with the specified raw
value, this initializer returns `nil`. For example:

    enum PaperSize: String {
        case A4, A5, Letter, Legal
    }

    print(PaperSize(rawValue: "Legal"))
    // Prints "Optional(PaperSize.Legal)"

    print(PaperSize(rawValue: "Tabloid"))
    // Prints "nil"

- Parameter rawValue: The raw value to use for the new instance.
