`/regexp` format to load multiple segments from precomputed skeleton

I have created a script to create a [precomputed skeleton with unsharded format](https://github.com/google/neuroglancer/blob/master/src/datasource/precomputed/skeletons.md), I have ~ 10k files numbered from `0`
to `12519` along with the `info` file in a locally served directory.

The example shows how to display 1 segment:

I have used the Rendering panel to add segments 1 by 1 from the web browser.

But how can I use the regexp syntax to load all or part of them at once?
