Set integration precision for diffuse Npred computation to 1e-5.
Apply deadtime correction in default npred methods.
Revert "Apply deadtime correction in default npred methods."

This reverts commit 7247c9a0b5f5976fb11206d4861f96d11f44a4c5.
Put back origin integration precision of 1e-4.
Put back original integration precision of 1e-4 and remove double deadtime correction.

Deadtime correction was applied in npred() and npred_radial(), npred_elliptical() and npred_diffuse(). The latter three methods all call npred() at the end, which led to a double correction of the deadtime. This has been corrected now.
Fix Npred integration precisions to 1e-5. Do not use m_eps anymore.

Fix all Npred integration precision to 1e-5 as this is needed for accurate results. Do not use m_eps for the integration precision anymore as each integrator may be optimized individually.
Correct reference value after bug correction in diffuse Npred computation
