duan_jandClaude Fable 5 94cd0d8080 Xtrapol8: add 1.2.9, ccp4 runtime dep, and missing modulefile env
XTRAPOL8_DIR and PATH were never set despite README referencing them;
upstream prerequisites require CCP4 alongside Phenix.

Xtrapol8 is software for the calculation of Fourier difference maps, extrapolated structure factors and estimation of the occupancy of at triggered state that occupies the crystal
at low occupancy. It is based on the cctbx toolbox and uses some CCP4 programs. In order to run Xtrapol8, you will need to have a proper licence for Phenix and CCP4 and have both
software suites installed. Please use Phenix 1.19 or higher.
An introduction into Fourier difference maps, structure factor extrapolation and the software itself can be found on the youtube channel of CCP4 (https://www.youtube.com/watch?v=H
