Add support for Ubeswap V3 farms

[jeanregisser]

We currently support V2 farms on Ubeswap, but the recently added V3 farms are missing.

https://app.ubeswap.org/#/earn/farms

As of writing this there's 1 V3 farm: UBE/CELO

• Address: https://celoscan.io/address/0xA6E9069CB055a425Eb41D185b740B22Ec8f51853

Contract details are available at: https://github.com/Ubeswap/ubeswap-v3-farm-protocol

@jeanregisser For the UBE/CELO farm should the hook return two position definitions (one for the position in the pool and one for the staking rewards) or a single one with token balances for pool position and stake rewards in UBE combined?

Hey @pbkompasz, 2 positions sound good!
Happy to assist more if needed.
