/**
The BIP class represents a 3-dimensional binary file stored using band sequential (BSQ) image encoding. The binary file is stored
such that X-Y "frames" are stored sequentially to form an image stack along the z-axis. When accessing the data sequentially on disk,
the dimensions read, from fastest to slowest, are X, Y, Z.
This class is optimized for data streaming, and therefore supports extremely large (terabyte-scale) files. Data is loaded from disk
on request. Functions used to access data are written to support efficient reading.
