MarcoFalke fa103db2bb scripted-diff: Rename SetHex to SetHexDeprecated 
SetHex is fragile, because it accepts any non-hex input or any length of
input, without error feedback. This can lead to issues when the input is
truncated or otherwise corrupted.

Document the problem by renaming the method.

In the future, the fragile method should be removed from the public
interface.
