Task:

Load the CSAFE Heptane Gas dataset from "csafe_heptane/data/csafe_heptane_302x302x302_uint8.raw", the information about this dataset:
CSAFE Heptane Gas
Description: A single time step from a computational simulation of a jet of heptane gas undergoing combustion.
Data Type: uint8
Data Byte Order: little Endian
Data Spacing: 1x1x1
Data Extent: 302x302x302
Data loading is very important, make sure you correctly load the dataset according to their features.

Visualize the combustion/fuel injection process:
1. Apply volume rendering with a hot colormap (black-red-yellow-white) to show temperature/density variations
2. Create an isosurface at the fuel-air mixture boundary (mid-range value)
3. Add a slice plane through the center to show the injection pattern
4. Adjust opacity to reveal the combustion core (opacity 0.4-0.6)

Please think step by step and make sure to fulfill all the visualization goals mentioned above.

Finally, save the paraview state as "csafe_heptane/results/csafe_heptane.pvsm"
