Add mapped assets in gated marketplace

[tlacloc]

Description

Currently, the gated-marketplace palette only accepts hashed assets in buy and sell offers. We want to update the palette to accept mapped assets from the mapped-assets palette instead of hashed assets.

Why

By updating the gated-marketplace palette to accept mapped assets instead of hashed assets, we can simplify the asset exchange process for users and reduce the complexity of the codebase. Additionally, this change will make it easier for developers to integrate with our system.

Changes

• Update the gated-marketplace palette to accept mapped assets from the mapped-assets palette in buy and sell offers
• Update the codebase to handle mapped assets correctly in buy and sell offers

Impact

Users will be able to exchange mapped assets in addition to hashed assets, making the exchange process more flexible and accessible
Developers will be able to integrate with our system more easily
The codebase will be simplified and easier to maintain in the long term

Additional Notes

It is important to ensure that the updated palette and codebase handle mapped assets correctly to prevent potential errors or security vulnerabilities.
This change may require updating documentation or user-facing materials to reflect the new asset exchange process.
