TypeScript enums

### 🔖 Enhancement description

Is there a way to, instead of generating enums, generate types and constants, e.g.

### 🎤 Pitch

From:
```
export enum ItemsRunItemOrigin {
TEMPLATE = 'template',
CARRYOVER = 'carryover',
ADHOC = 'adhoc',
}
```

to

```
export const ItemsRunItemOrigin = {
TEMPLATE = 'template',
CARRYOVER = 'carryover',
ADHOC = 'adhoc',
} as const;

export type ItemsRunItemOrigin = typeof ItemsRunItemOrigin[keyof typeof ItemsRunItemOrigin];
```
Thank you very much in advance
