fix: lifi fees same as shapeshift fees

[NeOMakinG]

Description

Li.Fi fees returned from the routes endpoint is returning a LIFI Shared Fee fees step which is the total affiliate fees

They share a part of these affiliate fees but I couldn't find a way to get how much they share, I asked on their discord (https://discord.com/channels/849912621360218112/1108511354253475872/1300968397336743936) and I'm waiting for an answer

During that time as we show double fees to our user, I did skip this step and only show ShapeShift fees which may be true but also wrong if Li.Fi take some fees from this amount

Risk

Medium, mainly presentational but could show wrong fees to users

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Testing

• Try a route with Li.Fi (ETH on Arb to FOX on Arb), it shouldn't show the Protocol Fees as this step contains only one protocol fee step which is the affiliate rates
• Try a bigger route like ETH on Arb to FOX on Ethereum, this route should display some protocol fees which is equal to the relayer this and should absolutely not be equal to the ShapeShift fees.

• Confirmed with @shapeshift/product this is the correct intent
• Confirmed the fee used as heuristics is the one we want to remove

• Confirmed the fee is gone from protocol fees
