Failsafe etelemetry import

[TheChymera]

Currently DANDI will fail to work due to this import specifically if etelemetry is not present. All other code points where etelemetry is needed are either caught exceptions or controlled by NO_ET.

Let me know if I should do this differently.

See #1400 regarding the test failures.

I don't think that failing test has anything to do with this -- likely change in pynwb or inspector, heh
