I’m sure there is a way to get the number of tracked parameters by Flux.Tracker, but so far I still haven’t found any way of actually getting this number.

Suppose I make the following:

```
forward = Chain(
Conv((5,5), 3=>16, relu),
x -> maxpool(x, PoolDims(x,(2,2))),
Conv((5,5), 16=>8, relu),
x -> maxpool(x, PoolDims(x,(2,2))),
x -> reshape(x, :, size(x, 4)),
Dense(200, 120),
Dense(120, 84))
```

How would I then go about finding the actual parameters this tracks?
