Fixed
Fixed data conversion errors in the Rust experimental implementation.
Changed ceil to floor to adopt a more conservative approach for calculating executed quantity in the PartialFillExchange model.

Fixed
Fixed cancellable condition (PARTIALLY_FILLED).

Added
Simplified data validation logic in data utils.
Added a new format conversion to support Rust implementation.

Added
An optional header argument has been added to Binance Historical Market Data converter in order to determine whether the first row is a header or not.

v1.6.4

Unresolved Tardis data processing problem that causes hang in backtesting is fixed. It needs regenerating normalized data to resolve the problem.
