New Features:
- Leapfrog integrator
- FFT zero-padding
- FFTs and gravitational wave spectra can now be computed on GPUs
- Gravitational wave spectrum output can be binned into bins of size k_IR
- Location of 2D slices can now be selected
- FOPT project: new piecewise potential
- New project: Axion only EOM
Changes:
- pySledgehamr: 3D output now read using 64-bit
- AMReX-based integrators temporarily disabled due to breaking changes in the AMReX repo
- Fix issues with the upsampling of input fields from hdf5 files
- FFTs now computed via the new AMReX FFT interface rather than SWFFT
- No CUDA-aware MPI for now
