Phantom fix

• Yarn would not build due to lot of legacy dependencies. Fixed by adding resolutions in package.json
• Phantom window API is updated. Connect listener array is not empty by default, so the check had to be removed- https://github.com/cykura/saber-common/commit/f081c239307590e61f91e0538e1ecd99e83e2da6#diff-1dea9b9e824f7c7aedc4f24fc2b7126af7b0dce8a63d78d5d376553067621048L66
• New use-solana package is installed from a tarball

Eager load pools

1. Call usePools() when the token pair is selected. This will fetch and save the pools in useState().
2. Pathway: usePools -> useV3SwapPools -> useAllV3Routes. This hook only needs currency in and currency out

• Further pathway: useAllV3Routes -> useBestV3TradeExactIn -> useDerivedSwapInfo

3. Read currency IDs from useSwapState, then feed it in useCurrency to obtain currency

Double call issue

1. On token change- swap/index.tsx -> useAllV3Routes
2. On input amount- swap/index.tsx -> useDerivedSwapInfo -> useBestV3TradeExactIn -> useAllV3Routes
3. useDerivedSwapInfo gives trade output amount, accounts and selected currencies
4. useBestV3TradeExactIn() takes input amount(with currency) and output currency
5. The two currencies are passed to useAllV3Routes()

Resolved by calling useAllV3Routes in useDerivedSwapInfo(). The routes as passed as a param to useBestV3TradeExactIn()
