update get_latest_ahrs_calibration priorities

@dsamtleben asked to take always the latest table instead of first sorting by the version number

This should be updated:

https://git.km3net.de/km3py/km3pipe/-/blob/master/km3modules/ahrs.py get_latest_ahrs_calibration

We probably, need now to iterate over all versions, parse them and take the "end" date. See, for example for this field here:

https://km3netdbweb.in2p3.fr/show_product_test.htm?oid=A02005424

Dorothea, d you think, this would it fit you?
