Changed default dll behaviour to be compatiable with chusanApp games

Removed reference to chuniio branch, as all versions of Dniel97 segatools now support the LED change

 ## chuniio-tasoller *with air tower LEDs*
 
 chuniio driver for tasoller custom 2.0 firmware

 thanks to:
-**akiroz** for the original code and USB Protocol information
-[**Dniel97**](https://gitea.tendokyu.moe/Dniel97) for rewritting my failed attempts at making this work
-
-the current implementation may not be fully arcade accurate, but should be visually acceptable during gameplay
-this should hopefully be addressed in the future
