fix(efcs): prevent uncommanded roll over 400kts

[lukecologne]

Summary of Changes

Fixes a small issue where the omega_0 of the roll law was going to either 0 or NaN, when exceeding 400kts CAS, due to the default setting in MATLABs interp1d function to not extrapolate (the maximum x-value of the LUT was 400kts). Now, extrapolation is active and points have been added to ensure a 0-gradient at the edges (i.e. the value remains constant below 0kts and above 400kts).
