Useless amount pointer in `encodeSwap`

[Clément Lakhal]

The endodeSwap function is using an extra variable to point where the amount1 starts, however since we are using static types, the value of the pointer will always be the same (proof: it's even hardcoded right now).

I suggest we should get rid of it.

Not closing this because this branch (https://github.com/primitivefinance/portfolio/commits/feat/mega) is actually bringing back pointers, both for the decodeSwap and decodeClaim.

Can close right?
