teukolsky_data: change TD_FAMILY_AE_TIME_ANTISYM

This is obviously not the data that A&E were using in their paper
(though the reason is unknown, as the free functions should be the
same), so stop referring to it as such. Also drop the constant
multiplier of 60 * \sqrt{2/pi}, since it has no other purpose than being
consistent with their data.
Name the resulting family TD_FAMILY_TIME_ANTISYM_CUBIC.

This is an API break.
