SDK: Liquidity Pools Transactions

[sophialittlejohn]

Implement transaction on LiquidityPool contracts:

• Invest
• Redeem
• Claim/Collect

Figure out how to fetch contract address instead of hard coding (e.g from router/pool manager --> fetch vaults = actual liquidity pool = combo of tranche and invest currency on a given domain)

Example (TBD, tranche curreny/domain may not be the same as on the pool):

pool.tranche(domain).invest(amount, ...)
pool.tranche(domain).redeem(amount, ...)
