[Feature Request] Support EIP-1193 Provider API

[BrettCleary]

Summary

As a user of web3.unreal, I would like to interface directly with a provider object in C++ or in Blueprints that matches the EIP-1193 spec and subscribe to its events.

Provider API Methods

• request
• on
• removeListener

Provider Events

• message
• connect
• disconnect
• chainChanged
• accountsChanged

Implementation

Currently only HyperPlay and 3rd party HTTP providers are supported for request only

Support for websocket provider connections to HyperPlay or 3rd party providers should be added

• or HTTP polling

Use Cases

• Listening to a contract event from client or server code in Unreal Engine
• Prompting the user to reconnect if a disconnect event is fired
• Updating the account address or chainId in game if the user changes which account is connected in hyperplay
