zwicker-group/py-pde: 0.51.0

Added first version of a torch backend. This backend does support basic differential operators and evolving PDEs, but it is not yet feature-complete. In particular, some special boundary conditions, interpolation, and some other special methods are not supported. Moreover, the torch backend has only be tested with CPU devices, but the long-term plan is to support GPUs, too.
