Major breaking change upgrade that requires a wipe of testnet:
* Improvements to efficiency and simplicity of margin calculations, should mean they are faster to compute and less bug prone
* Paving the way towards adding simulation utils which unblock important frontend metrics like estimated liquidation price on the order form (I know a lot of you have been asking for this)
* Important patches for subtle rust nondeterminism bugs which caused an outage the other day + some decimal rounding fixes
* Performance upgrades to the sequencer to get it from 200 TPS to 500 TPS (deferred state root computation)
* Adding new collateral assets such as JLP
