slice op error when axis = -1

[talebolano]

当使用ppq量化onnx模型时产生报错：

"ppq/executor/op/torch/default.py" , line 959
    new_axes = [ x if x >= 0 else len(data.dim()) + x for x in axes]
TypeError: object of type 'int' has no len()

貌似是slice的axis为-1时产生的问题

放假了别卷了，放完假再卷吧

去掉len()貌似正确了

new_axes = [ x if x >= 0 else data.dim() + x for x in axes]

问题已经在新的pr中得到修复 #88
