Introduce License Configurations for Group Restrictions

[kingster-will]

Description

This PR introduces two new license configuration items for groups: expectMinimumGroupRewardShare and expectGroupRewardPool. These configurations allow individual IPs to define restrictions for being added to a group.

• expectMinimumGroupRewardShare: Specifies the minimum percentage of the group’s reward share that must be allocated to the IP.
• expectGroupRewardPool: Specifies that the IP can only be added to a group with a specific reward pool. If set to address(0), the IP cannot be added to any group.

Key Changes

• New License Configurations: Added expectMinimumGroupRewardShare and expectGroupRewardPool to the LicensingConfig struct.
• Validation Logic: Implemented checks to enforce the new configurations when adding IPs to groups.

Objectives

• Restrict Group Addition: Allow IPs to define specific conditions for being added to groups.
• Ensure Compliance: Ensure that IPs are only added to groups that meet their specified reward share and pool requirements.

Implementation Steps

1. Update LicensingConfig Struct: Add expectMinimumGroupRewardShare and expectGroupRewardPool fields.
2. Modify Group Addition Logic: Implement checks to enforce the new configurations when adding IPs to groups.
3. Testing: Add tests to verify that the new configurations are correctly enforced.
