[BUG] "velocity_z" pointer field error in tutorial lightcones.ipynb

[raxquax123]

Describe the bug:
Attempting to run the lightcones.ipynb code provided in the tutorial Jupyter notebooks (or in the documentation https://21cmfast.readthedocs.io/en/latest/tutorials/lightcones.html) using the Python-wrapped code in the Github master branch returns the following error when calling the run_lightcone function:

Key velocity_z in PerturbedField(UserParams(BOX_LEN:512, DIM:384, FAST_FCOLL_TABLES:False, HII_DIM:128, HMF:1, KEEP_3D_VELOCITIES:True, MINIMIZE_MEMORY:False, NON_CUBIC_FACTOR:1, NO_RNG:False, N_THREADS:1, PERTURB_ON_HIGH_RES:False, POWER_SPECTRUM:0, USE_2LPT:True, USE_FFTW_WISDOM:False, USE_INTERPOLATION_TABLES:True, USE_RELATIVE_VELOCITIES:False);
CosmoParams(OMb:0.04897, OMm:0.3096, POWER_INDEX:0.9665, SIGMA_8:0.8102, hlittle:0.6766);
random_seed:315828138004;
redshift:12.124841861245521) not a defined pointer field in C.

To Reproduce:
Run the Jupyter notebook found at docs/tutorials/lightcones.ipynb using the current Python-wrapped 21cmFAST version from the Github master branch.

Details:

• Python version: 3.11.10
• OS: macOS 14.6.1
• Package: I’m using the Python-wrapped code from the master branch of the Github (as the version installed through conda does not include the new lightcone.py file, whose functions are called in the Jupyter notebook / readthedocs page).

Additional context
If I swap out the wrapper.py and outputs.py files for the conda-installed ones, then copy across these new lightcone functions introduced by the Github version into the two conda-based files, run_lightcone will run (although there are key errors later on when introducing RSDs).
I doubled the number of cells in each dimension compared to the default, but the resolution is the same. Using the default HII_DIM and BOX_LEN produces the same error.
I’m not sure if it’s an issue on my part with e.g. dependencies, or whether there is a bug!
