[CREDIX] Change Log:

Breaking:

• feat: credix pass now has flags instead of boolean fields in the struct. All the fields are exposed by functions.
• feat: withdraw epochs now do the rebalancing, the redeem base locked for investor calculation now take request amount and lp owned both into account. (withdraw request account was removed from contexts)
• feat: Repayment schedule's periods now have calculation date. Describing on what date the accrual will be calculated from.
  feat: Membership fee calculations are not based on the yearly outstanding principal
• feat: Program State now has credix treasury. Credix treasury is where the credix fees will be collected from now on.

For Integrators:

Required changes for integrators in there smart contract:

• If any field example(is_active, is_investor) from the credix pass is used. Replace it with (is_active(), is_investor()...)

• Remove withdraw Request accounts from the cpi calls.

• Mark withdraw epoch mutable if it is already not when creating withdraw request or redeeming withdraw requests.

• For Redeem withdraw request and withdraw funds. Change the credix_muiltisig -> credix_treasury. And Credix_muiltisig_token_account-> credix_treasury_token_account. The correct credix_treasury address is in program_state account of credix program.

• To get the max amounts that can be withdrawn in the withdraw Epoch. We have provided a function in the rust client.

Changes required for there local setup:

• When sending the repayment schedule with set_repayment_schedule we can directly send the RepaymentPeriod instead of RepaymentPeriodsInput struct which previously existed. The calculation_date in the periods can be set equal to the period's time_frame.start.
