Detailed Description

Creates Carna::base::HUVolumeUInt16 object from HUGZ-file.

HUGZ File Format

The HUGZ file is GZIP compression of the following data:

1. Bytes 1 to 4 are an unsigned integer that describes the volume width.
2. Bytes 5 to 8 are an unsigned integer that describes the volume height.
3. Bytes 9 to 12 are an unsigned integer that describes the volume depth.
4. Bytes 13 to 16 are an IEEE 754 single precision floating point number that describes the x-spacing.
5. Bytes 17 to 20 are an IEEE 754 single precision floating point number that describes the y-spacing.
6. Bytes 21 to 24 are an IEEE 754 single precision floating point number that describes the z-spacing.

7. Each voxel is represented as a signed short.

   Todo:

   Use int16_t instead of signed short.
