Anvred corrections for single crystal

[Vickie Lynch]

New algorithm, AnvredCorrections, to do spherical absorption corrections. The pixel and wavelength corrections will be optional if the data has not been divided by vanadium. Following A.J.Schultz's anvred, the weight factors should be:

• sin2(theta) / (lamda4 * spec * eff * trans)
• where theta = scattering_angle/2
• lamda = wavelength (in angstroms?)
• spec = incident spectrum correction
• eff = pixel efficiency
• trans = absorption correction

(In [12604]) Refs #3193 Anvred correction are implemented for historgrams, but not finished for events; have not compared results with ISAW

[Vickie Lynch]

(In [12610]) Refs #3193 Same anvred corrections for histograms and events

[Vickie Lynch]

(In [12633]) Refs #3193 Power correct for weights; interpolation removed; checkbox renamed to OnlySphericalAbsorption

[Vickie Lynch]

(In [12634]) Refs #3193 BuildLamdaWeights arguments changed

[Vickie Lynch]

(In [12649]) Refs #3193 add detector id to EventLists and do corrections in place for events

[Vickie Lynch]

Matched these corrections from IsawEV with this algorithm. Data was TOPAZ_2511, power=3, Radius=0.17, smu scattering =1.302, amu absorption=1.686 for detector id = 3245368.
