Make some sections of the corrugated foil thinner

Make the corrugated foil partly thinner.

• design:

• implementation:

Green thick part: average thickness (

$\frac{\sum\rho_i l_i}{\sum l_i}$

) before scaling 0.995 g/cm^3, scale factor 200/250

Pure	Body Density $\rho (g/cm^3)$	Thickness $l (um)$	Area density $\sigma=\rho\times l (g/m^2)$
Woven material	0.995	200	199.0(100%)

Ren thin part: average thickness before scaling 2.2121 g/cm^3, scale factor 70/250

Mixture	Body Density $\rho (g/cm^3)$	Thickness $l (um)$	Area density $\sigma=\rho\times l (g/m^2)$
Woven material	0.995	20	19.90(12.85115%)
Aluminium	2.699	50	134.95(87.14885%)

• Among the TnT id from 101-271, for each 19 sectors in a column, the 2-18 are thinned, including: 102-118, 121-137, 140-156, 159-175, 178-194, 197-213, ...
• with regular pattern: 10[2-9]|11[0-8]|12[1-9]|13[0-7]|14[0-9]|15[0-69]|16[0-9]|17[0-58-9]|18[0-9]|19[0-47-9]|20[0-9]|21[0-36-9]|22[0-9]|23[0-25-9]|24[0-9]|25[0-14-9]|26[0-9]|270

Many thanks indeed for this @gwan, it looks really great from a quick glance. Sorry I haven't had time to look at this in detail yet but will try to do so later today.

A couple of immediate reactions:

• I thought that the thick part was 200um CF + 50um Al but you don't have the Al part here? - ignore this, my mistake, I hadn't seen the latest amendments from Todd
• There appear to be Iris-foil-related changes here, which should probably be in a separate MR?
