fix(bpp): overwrite turn signal by latter module (#7045)

* fix(bpp): overwrite turn signal by latter module Signed-off-by: satoshi-ota <[email protected]> * fix(avoidance): return previous module turn signal if it's in success state Signed-off-by: satoshi-ota <[email protected]> * fix(avoidance): don't output turn signal if there is huge lateral deveation Signed-off-by: satoshi-ota <[email protected]> * refactor: small update Signed-off-by: satoshi-ota <[email protected]> * chore: use lower case Signed-off-by: satoshi-ota <[email protected]> * refactor: remove redundant function call Signed-off-by: satoshi-ota <[email protected]> --------- Signed-off-by: satoshi-ota <[email protected]>
