new hdmf version breaks pynwb

[djkapner]

@dougollerenshaw found this this evening:
a fresh install will pull down hdmf 2.5.0. This breaks pynwb/allensdk in some ways.

Tasks:

• add an hdmf<=2.4.0 to requirements.txt
• make that change in master, roll a minor release
• rebase rc/2.11.0
• contact pynwb

To reproduce, in a fresh env:

>>> from allensdk.brain_observatory.behavior.session_apis.data_io import BehaviorLimsApi

Sorry about that. We are working on a release to pynwb to account for the change and we plan to release it tomorrow morning. PyNWB will then pin a particular version of hdmf to prevent these incompatibilities in the future.

FYI: The PyNWB/HDMF team have released HDMF 2.5.1 on PyPI and conda-forge. This release reverts the breaking change. We have yanked HDMF 2.5.0 from PyPI and are in the process of marking it as broken in conda-forge. Sorry for the trouble.
