Add Licensing Module

[Ramarti]

Licensing Module:

A set of contracts that enables the creation and configuration of licenses to govern IPAssets in Story Protocol.

Contracts

LicensingModule

Allows a Franchise owner to configure the licensing rules for an IPAssetRegistry

IERC-5218

A modified version of the rights management draft

RightsManager

Our IERC-5218 implementation.

• Allows us to grant 2 type of licenses:

1. Rights: Licenses tied to a tokenId (IPAsset id), in which the license holder is always the owner of the tokenId. Each tokenId can a commercial or non commercial license tied to it
2. Tradeable Licenses): The license holder is the owner of the correspondent LicenseRegistry NFT. They are either:
   2.1 Franchise root license: LicenseRegistry enabled license minted by a Franchise owner to govern commercial or non commercial rights for all the IPAssetRegistries.
   2.2 Sublicense: a license coming from Rights or other Licenses, minted by the parent license owner. These would be the future "movie adaptation" type licenses that can be sold.

• Creates a LicenseRegistry on initialization
• Executes licensing terms to activate the license.
• Tracks active licenses along the license trees.

LicenseRegistry

Simple NFT that tracks ownerships of type tradeable licenses emitted by IPAssetRegistry

Terms

Contracts that define what need to happen on chain for a license to be active. These could be:

• Timing terms (license valid from start date to start date + ttl) <-- implemented
• Oracle verifications
• Payment
• Relationship creation
• etc

Tasks in this PR

• LicensingModule (config) contract
• IERC5218 with modifications
• RightsManager
• IPAssetRegistry is RightsManager, will grant rights to LicensingModule config for the franchise
• LicenseRegistry NFT for sublicenses
• Generic on chain licensing term processors (ITermProcessor)
• Aggregator of terms (MultiTermProcessor)
• Link terms with RightsManager
• Add terms execution to activate licensing
• Add timing terms (TTL)
• Test Licensing contracts
• Test terms

For later:

• Add Terms contract that will try to create a relationship
• License off chain metadata

Closes #67
