RatedSwapPool for stNEAR/wNEAR pool

Based on StableSwapPool source code

Major changes:

added rates to swap & add/predict/remove_liquidity calculations
math upgraded to 24 decimals using U384
rates acquired from another smart contract via cross-contract call

New external methods:

add_rated_swap_pool
add_rated_liquidity
rated_swap_ramp_amp
rated_swap_stop_ramp_amp
get_rated_pool [view]
predict_add_rated_liquidity [view]
update_pool_rates

Add liquidity flow:

call get_rated_pool & check rates are actual
call predict_add_rated_liquidity with actual rates
batch-call [update_pool_rates, add_rated_liquidity]

Remove liquidity flow:

same as StableSwapPool

Swap flow:

get_return (add rates?)
batch-call [update_pool_rates, swap]
