JSON Merge Patch

The library supports JSON Merge Patch (RFC 7386) as a patch format. The merge patch format is primarily intended for use with the HTTP PATCH method as a means of describing a set of modifications to a target resource's content. This function applies a merge patch to the current JSON value.

Instead of using JSON Pointer to specify values to be manipulated, it describes the changes using a syntax that closely mimics the document being modified.

??? example

The following code shows how a JSON Merge Patch is applied to a JSON document.

```cpp
--8<-- "examples/merge_patch.cpp"
```

Output:

```json
--8<-- "examples/merge_patch.output"
```
