maybe soundxyz-filter-contracts and sound-protocol-filter-contracts can be the same generic strategy but with different inputs

• it seems to me that we're unnecessarily duplicating code here:
• https://github.com/neume-network/strategies/tree/main/src/strategies/soundxyz-filter-contracts
• https://github.com/neume-network/strategies/tree/main/src/strategies/sound-protocol-filter-contracts
• as these strategies look very much alike but potentially have a difference in constants
