Inspection of the code shows this is broken.

s/data/le_buffer.get()/

I think the corresponding code in readFileRaw is broken too. The data is read into le_buffer but then never copied into data.

It seems dangerous to support big-endian if you're not planning to test it. Maybe just rip this out and throw an exception?
