Introduce pipe_v24 geometries.

Macro allows binaries to be generated at arbitrary angles.
Outer casing of bellows assembly removed. 
Geometries v24e, v24f, v24h, v24i are provided.

pipe/pipe_v24e.geo.info

+Created by macro: macro/pipe/fair/create_bpipe_geometry_gen.C
+Parameters: geoTag=v24e, beam_deflection_angle=1.89
+
+The downstream section has maximum deflection at the bellows.
+
+May be used for low beam energies from 5 AGeV gold-gold collisions
+at 100% MF and below.
