* Transforms a Slice Zone using a set of mapping functions, one for each type
* of Slice. Mapping functions can be async.
*
* Whenever possible, use this function on the server to minimize client-side
* processing.
*
* @example
*
* ```typescript
* const mappedSliceZone = await mapSliceZone(page.data.slices, {
* 	code_block: ({ slice }) => ({
* 		codeHTML: await highlight(slice.primary.code),
* 	}),
* });
* ```
