Options
Options are a special case of enums. It is simply either a 0 for a None option and a 1 plus the value
for a Some option.
Examples:
| Type | Value | Encoded Value |
|---|---|---|
| Option | None | 0x00 |
| Option | Some(false) | 0x0100 |
| Option | Some(true) | 0x0101 |
| Option<vector | None | 0x00 |
| Option<vector | Some([1,65535)) | 0x01020001FFFF |
