feat(sdk-core): Add Base Sepolia constants

This adds the Chain ID, Addresses, and WETH token configuration for the Base Sepolia network (84532). This uses the addresses referenced in the Base Deployments doc: https://docs.uniswap.org/contracts/v3/reference/deployments/base-deployments This also uses this as the source for the WETH token on base sepolia: https://sepolia.basescan.org/token/0x4200000000000000000000000000000000000006 This is following up on the changes that were being made on the old SDK repos: Uniswap/sdk-core#110 Uniswap/smart-order-router#494
