[Feature Request]: Reexposing groups and statuses like `is_pinned`.

[cenk1cenk2]

What?

Hello @akinsho,

Thank you for maintaining this plugin for such a long time.

With the latest changes, "bufferline.groups" no longer expose the groups for manipulation/look-up except for testing. If it is not much of a hassle can these be reexported?

I might be missing the other way to implement this but thank you so much for your time either way.

Why?

I know this is the internal API of the plugin but I have been heavily using it to implement functionality like closing all buffers but current except for the pinned ones, maybe that would be the case for others too.

These use cases like closing all but current were discussed in an issue before and you have indicated that this is easily implementable. Still, with the API no longer exposing them, it is impossible to do so anymore.
