The Membrane.File.Sink.Multi element writes buffers to a set of files, switching files based on specified events. It provides options for configuring file naming, extensions, and split events.

```APIDOC
## Membrane.File.Sink.Multi Element Documentation

### Description
Element that writes buffers to a set of files. File is switched on event. Files are named according to `naming_fun` passed in options. This function receives sequential number of file and should return string. It defaults to `path/to/file0.ext`, `path/to/file1.ext`, ...
The event type, which starts writing to a next file is passed by `split_event` option. It defaults to `Membrane.File.SplitEvent`.

### Element Options
Passed via struct `Membrane.File.Sink.Multi.t/0`

#### Path Parameters

* **location** (Path.t()) - Required - Base path to the file, will be passed to the naming function.
* **extension** (String.t()) - Optional - Extension of the file, should be preceeded with dot (.). Defaults to `""`. It is passed to the naming function.
* **naming_fun** ((Path.t(), non_neg_integer(), String.t() -> Path.t())) - Optional - Function accepting base path, sequential number and file extension, and returning file path as a string. Default one generates path/to/file0.ext, path/to/file1.ext, ...
* **split_event** (Membrane.Event.t()) - Optional - Event causing switching to a new file. Defaults to `Membrane.File.SplitEvent`.
