Using a group prefixed with `-` causes lstrip issue

Numcodecs version

N/A

Python Version

3.8.17

Operating System

Linux

Installation

Installed via pip

Description

Not sure about what version of Numcodecs I'm using, but my issue happens whenever a group is named "-1". The exact exception is: AttributeError: 'list' object has no attribute 'lstrip'

And the stack trace is:

Steps to reproduce

call write_image from ome.zarr package with a group named "-1".

Additional output

No response

I'm wondering if somwhere there's an attempt to cast the node name as an integer (assuming greater-than zero chunk names). Can you reproduce this issue without ome-zarr-py?

Closing because we don't have a reproducer and 2.15 is now quite old.
