[Feature]: Port improvements in GenericDataChunkIterator from NeuroConv

[rly]

What would you like to see added to HDMF?

The CatalystNeuro team has added helpful utility functions to the GenericDataChunkIterator in NeuroConv: https://github.com/catalystneuro/neuroconv/blob/5bee4c7d69101d1f9cb13d2aa27ae0e7425cc55a/src/neuroconv/tools/hdmf.py#L15

What solution would you like?

We should incorporate these improvements in HDMF and add SliceableDataChunkIterator as a concrete implementation. Do you have any concerns with this @h-mayorquin ?

Do you have any interest in helping implement the feature?

Yes.

That sounds like a good idea to me.
