New split payment options for linked accounts

We expanded the list of available methods in which payments can be split between linked line of credit accounts and installment loans, providing greater flexibility in how you allow customers to make payments. Five new options are now available:
- Highest Payoff Balance: prioritizes accounts with the largest payoff balance first.
- Lowest Payoff Balance: prioritizes accounts with the smallest payoff balance first.
- Highest Principal Balance: prioritizes accounts with the largest principal balance first.
- For line of credit accounts, the total balance is used.
- Lowest Principal Balance: prioritizes accounts with the smallest principal balance first.
- For line of credit accounts, the payoff balance is used.
- Highest Interest Rate: prioritizes accounts with the highest interest rate first.
- For line of credit accounts, the primary bucket interest rate is used.
