JamesPHoughton/pysd: 3.5.0

New Features Add support for subscripted arguments in pysd.py_backend.functions.ramp() and pysd.py_backend.functions.step() (issue #344). Bug fixes Fix bug related to the order of elements in 1D GET expressions (issue #343). Fix bug in request 0 values in allocate by priority (issue #345). Fix a numerical error in starting time of step and ramp. Documentation Include new PySD logo. Internal Changes Ignore 'distutils Version classes are deprecated. Use packaging.version instead' error in tests as it is an internal error of xarray. Add a warning message when a subscript range is duplicated in a variable reference
