Add Local CICO options in Brazil to the Add/Withdraw Flow

[nityas]

Expected Behavior

Users in Brazil have 2 local CICO options (not integrated in Valora) that should be listed to users in that country

• Bitfy: CICO for cUSD/BRL via Bitfy app [LIVE] - https://bitfy.app/
• FlowBTC: exchange in Brazil working to get cUSD and CELO listed by the beginning of April 2021 [WIP, Co-Marketing campaign is live] - https://www.flowbtc.com.br/ (should be https://www.flowbtc.com.br/celo.html but not live yet)

Current Behavior

Users in Brazil only see global options in the CICO flow
