FUN-411. Double royalty pool

[Bromel777]

This pull request introduces a new type of pool called Double Royalty Pool. Generally, the Double Royalty Pool is an extension of the existing Royalty Pool, with a few key additions:

New royalty pool fields (line 76)
Field for a second royalty public key (line 81)
All existing royalty pool math now takes these new fields into account, for example:
Royalty calculation logic updated (line 227)

The following contracts were also updated to support the new royalty model:

PDoubleRoyaltyDeposit.hs
PDoubleRoyaltyRedeem.hs
These contracts take the new fields into account in their calculations.

The PDoubleRoyaltyWithdrawPool.hs contract (which validates royalty withdrawals) now works with two royalty keys and determines the correct withdrawer based on a value provided in the redeemer.

Additionally, the Royalty Pool DAO v1 contract was extended to support the new format. It now validates and prevents unauthorized changes to the new fields during DAO actions.

New scripts:
PDoubleRoyaltyDAOV1.hs
PDoubleRoyaltyDeposit.hs
PDoubleRoyaltyPool.hs
PDoubleRoyaltyRedeem.hs
PDoubleRoyaltyWithdrawPool.hs

This PR also includes a small fix for the following contracts related to the DAO v1 orders approach:

PBalancePool.hs
PPool.hs
A Nonce field was added to the pool datum in both cases to support new DAO-related flows.
