Consider adding WAMPL deposit support

[LifeOfCypher]

Most non-technical users do not want to hold Raw ample because of the fluctuating supply. Allowing for WAMPL deposits will increase the funds deposited into the vault.

This will also require a wrapper function to unwrap the WAMPL back to AMPL.
