This pull request adds sparse conv2d(1*1) support for auto_scheduler. I have implemented sparse conv2d with kernel_size=1, using the BSR sparse data format.
I evaluate the performance of sparse conv2d by mobilenet_v2 in pixel2. All of 1*1 conv2d in the network are transformed into sparse conv2d with block_size=(4, 1).
