soroban-cli: add support for updated simulateTransaction responses

[tsachiherman]

What ?

The rs-soroban-env now contains library functions to calculate the fees needed by a transaction, based on it's resources.
Our goal is to integrate that into simulateTransaction endpoint in soroban-rpc. This issue is about the third step in the process:
We need to update the soroban-cli to use the updated soroban-rpc simulateTransaction endpoint.

Implementation notes:

The Quickstart image with the soroban-rpc is already ready to be used. Invoke it with

docker run --rm -it -p "8000:8000" --name stellar stellar/quickstart:pr-444-soroban-dev-arm64 --standalone --enable-soroban-rpc --enable-core-artificially-accelerate-time-for-testing

Then, follow the guide in https://soroban.stellar.org/docs/getting-started/deploy-to-a-local-network, creating an account.

Last, ensure that all the following commands works:

• soroban contract deploy
• soroban contract install
• soroban contract invoke
• soroban lab token wrap
