Confusing RAMP_INIT / PULSE_INIT

[n01r]

The RAMP_INIT/PULSE_INIT parameter inside laser.param that controls how far from the plateau / peak the laser pulse is initialized still causes major confusion in my opinion.

@PrometheusPi said he is responsible for the initial implementation and has valiantly offered to make everything more clear. :crossed_swords: :shield: :+1:

I would say, in terms of simplification we should make sure that the following requirements are fulfilled by the new implementation:

• [ ] a single conversion with an obvious (to every user) conversion factor gives the initialization time in seconds
• [ ] the initialization time conversion factor stays reasonable for all microscopic or macroscopic setups
• [ ] the parameter is consistently named throughout all laser profiles
• [ ] all example .param files are updated with documentation changes as well
• [ ] the documentation shows clearly how to do the conversion to time in SI units
• [ ] the sphinx documentation needs to be updated: docs/source/usage/workflows/laserPeakOnTarget.rst
