fastfunc 0.1.6

Fast numpy ufunc operations

fastfunc

NumPy's own ufunc operations are handy, but can be quite slow (see https://github.com/numpy/numpy/issues/5922 and https://github.com/numpy/numpy/issues/11156). Use fastfunc as a drop-in replacement

# import numpy
# numpy.add.at(target, idx, vals)

import fastfunc
fastfunc.add.at(target, idx, vals)

to get a speed-up by a factor of 40.

This is achieved by moving the operations to C++ using pybind11.
