move delay out of integration loop

[JohnWangDataAnalyst]

to speed up fitting and keep the same fitting results

[JohnGriffiths]

@JohnWangDataAnalyst please take a closer look at the effects of big code base changes like this

I ran with the updated code and the only example that depends on this function seems to have gone very skew

This is what it looks like without the delays change

Also, worth noting, I don't think the orig example shown there is quite looking as it should either.

Please look into these things and lmk where you get.

LEd_p2e = LEd_p2e + ptmatmul(dg_f, E - I)
I think it is here... the same variable is used in the integration loop.
solution: LEd_p2e = Ed_p2e + ptmatmul(dg_f, E - I) and redefined the ED_p2e in the window loop
similar to other populations I and P
you want to change it directly or want to get a new PR?

closing, will be resumed on a new PR
