Support for the OptaSense ODH4 HDF5 format.

This layout is produced by OptaSense ODH-4 interrogators and is used, for example, by the University of Wisconsin-Madison SURF (Sanford Underground Research Facility) deployment contributed to the PubDAS Global DAS Month (February 2023) dataset.

Each file holds a single “raw_data” dataset of shape (channel, time) whose root attributes carry the acquisition metadata: start/end times, sampling rate, channel range and spacing, gauge length, raw data units (phase shift in radians), and the scale factor to strain.
