fix cudaErrorIllegalAddress

1

Use `cfg.n_rays_per_batch` instead of default `n_rays_per_batch` 4096 in `JNeRF/python/jnerf/models/position_encoders/hash_encoder/grid_encode.py` which may cause cudaErrorIllegalAddress below when `cfg.n_rays_per_batch` much greater than 4096. ``` code=700( cudaErrorIllegalAddress ) cudaMemcpy(a.ptr, var->mem_ptr, var->size, cudaMemcpyDeviceToHost) ```
