Add a function to free allocated memory (#52)

Managed runtimes like C# P/Invoke requires this in order to be able to correctly free memory in managed code that was allocated by unmanaged code. The method was only defined in copentime because it can be used on it's own but opentimlineio must be used with opentime. Signed-off-by: Félix Bourbonnais <[email protected]>
