Increase braking to ISO 15622-2018; tune accelerating.

I changed the DP acceleration profile in 0.8.8. After that, compared to stock openpilot acceleration profile, when using DP profiles, my car still occasionally unable to stop behind stationary cars. Therefore I increased decel curve to what ISO 15622-2018 writes, leaving braking to the model, and I've tested 300km.

Please try this profile on your cars before merging.

if you can test it on 0810 once its out then we can probably merge it since it has retuned mpc

I've give it a retry. About a week.

The acc&dec profile is working in 0.8.10, both with and without lead cars. However, my CorollaH TSS2 is suffering more from insufficient acceleration in 0.8.10. Please close this PR for now or merge it into 0.8.9.

Would this braking change also apply to GM cars? I switched to 8.10 cause 8.9 was trying to rear end everyone with my 2017 GM Volt.

I actually answered this question myself. I jumped over to https://github.com/wer5lcy/openpilot/tree/Re-tune-DP-braking-curve and the issue of trying to run into the backs of cars came back. It seems like its not braking with the physical brakes only the regenerative braking only. Stock long does not have this issue as the current 8.10 works fine as far as braking goes.
