use change_scaling method to change scales

Changing the header scales directly worked until laspy 2.1.0.
In 2.1.0 the header scales and the scales of the points object
of type `ScaleAwarePointRecord` would get out of sync
when not using `change_scaling`.
That method exists since laspy 2.0.0, so there should
be no breaking change
