Goal of this PR is to unify MarketPosition type across FPMMs and the Orderbook.
This is done by using the ConditionalTokens ERC1155 tokenId as the primary identifier for a position.
Refactor MarketPosition:
Add utility function to generate the tokenId from conditionId + outcomeTokenCount + collateral
Remove tight coupling with FixedProductMarketMaker and replace with tokenId
Rewrite updateMarketPosition* functions so that they use tokenId
Update Exchange:
Implement updateMarketPositionFromOrderFilled to create/update a MarketPosition given an OrderFilled event
