Core package base -- placeBid and listToken

[antho1404]

Description

This PR creates the foundation for the new @liteflow/core package that will provide all the features associated with the API but any javascript/typescript application. This will complement the current @nft/react that can only be used in react.
The goal is that @nft/react will use @liteflow/core and eventually be renamed.

In this PR, I only focused on the general architecture and the creation of offers with

• placeBid
• listToken

Regarding architecture, we have a general client with modules like the exchange with specific actions.
This can be initialized like

new Client(new URL('https://...')).exchange.placeBid(...)

I also updated the hook library to initialize this client (for now alongside the other existing client) and use the core lib to execute the actions in the useCreateOffer

How to test

Build the library and play with some scripts or update the starter kit by linking these libraries and trying to create a new listing and/or a new bid.
