Simulate Endpoint Integration

[mangoplane]

Hi,

It would be useful to implement a Simulate Endpoint for enhanced debugging of transactions issued by this SDK. Simulate is summarized here:

https://developer.algorand.org/articles/whats-new-in-algorand-3150/#new-simulate-endpoint

In the Algod REST API, it's defined here:
https://developer.algorand.org/docs/rest-apis/algod/#post-v2transactionssimulate

My understanding is it's just adding a REST interface to this endpoint, and dressing up the result to work with the SDK types.

Happy to have a go at implementing this, unless you would prefer to take care of this :)

Simulate endpoint is still a WIP from algod.

Updating the V2 kr V3 endpoints is semi automated.
