Integrate chain simulator into xSuite

[raress96]

• New package xsuite-chain-simulator was added.
• xsuite-chain-simulator is an optional dependencies of the xsuite package
• New CSProxy, CSWorld, CSContract and CSWallet classes were made similar to SProxy etc

The xsuite-chain-simulator-temp package is for testing ONLY and need to be removed before this is merged.

Notes to myself:

1. Once all the feedback above is discussed / taken into account, review more closely CSProxy and CSWorld.

2. Thinking about changing the name "chainsimulator" to something else. Maybe "lightSimulnet" / "simulnet"?

3. Review CSWorld.ts once all the other feedback is taken into account.

4. CSWorld / CSProxy should implement at least the functionalities of SWorld and SProxy. For example, createContract is missing.

@lcswillems One thing I noticed now that I re-added the Hatom tests is that the world.createWallet function will always create the wallets in Shard 0 due to the way it generates addresses. So for the Hatom tests I had to manually input an address which is on Shard 1 for everything to work sync.

I am thinking that maybe in the future the world.createWallet function of the CSWorld could also take an optional Shard argument to create a wallet in a specific shard? Something to keep in mind for the future.

That's a good idea. WIll think more about it

It seems the CI doesn't pass.

Things to be fixed upstream in the chain simulator repo:

• config. We should not have to set the min stake to be 1 EGLD in our own config.
• process-status doesn't work properly when metachain call fails.

Things to be fixed in xSuite:

• correctly implementing tx status in cases 1, 2, 3, 4
