/** This class implements reading of ENVI hyperspectral files. These files can be stored in multiple orientations
(including BSQ, BIP, and BIL) in order to optimize streaming speed depending on applications. Basic ENVI
files are stored on disk as a large binary file with a corresponding header. Code for reading and processing
ENVI header files is in the envi_header class.
