NautilusTrader 1.107.0 Beta - Release Notes

The main thrust of this release is to refine some subtleties relating to order
matching and amendment behaviour for improved realism. This involved a fairly substantial refactoring
of SimulatedExchange to manage its complexity, and support extending the order types.

The post_only flag for LIMIT orders now results in the expected behaviour regarding
when a marketable limit order will become a liquidity TAKER during order placement
and amendment.

Test coverage was moderately increased.
