* WIP: Implementation of the remainder of stablecurve methods
* Edits based on PR feedback
* revert SwapVersion
* PR fixes
* checked add / sub
* reverted to using RoundDirection instead of LiquidityProviderOperaiton
* removed LiquidityProviderOperation enum
* Revert flipped parameters
* initial attempt at noramlized_value
* use d for noramlize value for stable curve
* TradeDirection instead of RoundDirection for trading_tokens_to_pool_tokens
* reimplemented the trading_tokens_to_pool tokens function for stable
* Typo
* fix rounding errors in pool_tokens_to_trading_tokens
* try different values of amplification factor in test for stable curve
* fixed broken tests, use constant_product normalized_value function
* use cubic solver
* fix noramlize_value function bad maths
* redid noramlized value for one last time
* added more proptests
* Get tests to work
* Fixup for prod usage
