Warn users of asymmetric liquidity adds and removals about slippage

[jkbrooks]

Is your proposal related to a problem?

When users asymmetrically add or remove liquidity they incur slippage because they execute a swap and then pool symmetrically. This removes the total value they own but they are unaware. Multiple investors have complained about this but we have not yet clearly indicated it, which is a good sign that the project would not be ready for larger whales to pool asymmetrically after a mainnet.

Describe the solution you'd like

Post a text warning for any asymmetric liquidity adds or removals indicating that the user will execute a swap followed by a symmetrical add or withdrawal. Note that this will incur swap fees and slippage.

Describe alternatives you've considered

We could also actually show users how each step works so they can see how much they'd give up in slippage prior to a swap. (Would take more time)

Additional context

let's get this done before mainnet
