I found myself needing a Let pattern for some object detection work. Thanks for taking a look!

I wonder, do we need to match against the let bound variable? Isn't it always Var? Not sure if relay Let supports pattern destructing on let lhs, like let (x, y) = ... in body

@masahi I agree the Expr will always be a var, but I wanted to let users match on more complicated attributes like name/dtype/shape/etc, so I left it a general in pattern
