Add EIP-5773: Multi-Resource Token standard (#5773)

* Propose Multi-Resource Token standard RMRK team has developed a next step in NFTs where one NFT can be tied to multiple resources. * Address issues reported by EIP repository's CI * Fix styling discrepancies in section titles * Address CI's issues in the preabmle * Add discussion URL * Fix discussion URL formatting * Add the EIP number * Fix getResourceMeta specification * Apply changes based on PR comments * Replace "primitive" with a clearer explanation Co-authored-by: Pandapip1 <[email protected]> * Apply changes based on ECH call #5 Applied the changes based on feedback received on the EIP Editing Office Hour Meeting #5. This commit includes changes to the proposal as well as adds an exaple implementation to assets/ directory. * Address the stylistic issues reported by the CI * Fix a reference to EIP-712 * Minor typo fixes * Updates `getResourceMetadata` description Co-authored-by: Sam Wilson <[email protected]> * Rename MultiResource -> MultiAsset and relicense The proposal was renamed to Context-Dependent Multi-Asset Tokens to better illustrate its function. Another example was added to represent the possible IoT usecase and the explanation on the naming decision was added to the rationale. The examples were relicensed to CC0, to conform to the requirements of EIP repository. * Fix license identifier & Specification contract title * Fix indexes of Rationale questions * Minor polishing of the rationale * Update references to assets to use an istead of a in Rationale * Final polishes Co-authored-by: Pandapip1 <[email protected]> Co-authored-by: Steven Pineda <[email protected]> Co-authored-by: Sam Wilson <[email protected]>
