* initial implementation for conv_transpose ran pre-commit implemented conv_transpose updated conv_general docstring updated conv_general docstring updated code comments removed commented run_conv_checks updated acknowledgments added missing entry to ops.rst added op to nn.layers resolved merge conflicts * removed ConvolutionTranspose primitive as suggested by reviewer removed ConvolutionTranspose primitive as suggested by reviewer * remove transpose flag, add another test --------- Co-authored-by: Awni Hannun <awni@apple.com>
