Function EnumType

EnumType<const N extends string, const O extends readonly string[]>(
name: N,
options: O,
): { type: "enum"; options: O; name: N; numBits: number }
Create an enumeration type with a fixed set of string values.

Enums are encoded using the minimum number of bits needed to represent all options. For example, 4 options use 2 bits, 8 options use 3 bits.
Type Parameters
- const N extends string
- const O extends readonly string[]
Parameters
- name: N
  The type name (must start with uppercase, e.g., "Direction")
- options: O
  Array of string values for the enum
Returns { type: "enum"; options: O; name: N; numBits: number }
Example
```
const Direction = EnumType("Direction", ["up", "down", "left", "right"]);
const Status = EnumType("Status", ["pending", "active", "completed", "failed"]);

const Player = ObjectType("Player", {
  facing: ReferenceType(Direction),
  status: ReferenceType(Status),
});
```
