extends BaseCarSspeKernel

Description: 长城新项目使用：信号处理内核151及其之后版本，2mic4Zone 信号处理方案 参考CarFourMicSspeKernel.java 此类为2mic4zone后排抑制专用的Kernel 注意，必须符合以下条件才可以使用：（重要事项） 1.2mic设备，且打开了后排抑制 2.信号处理资源必须为2mic4zone的后排抑制定制资源

抑制需求逻辑： doa = 1，抑制副驾以及后排 doa = 2，抑制主驾以及后排 doa = 3/4，绝对抑制不可支持唤醒&识别

用户侧用法逻辑： 1. 程序启动后，根据 后排抑制开关状态，判定当前使用左右音区资源 or 后排抑制资源 2. 左右音区资源(新)：CarTwoMicNewSspeKernel 后排抑制资源(新)：CarTwoMic4RegionSspeKernel 3. 后排抑制开关打开的情况下，还需要判断用户修改音区锁定的开关状态 如果锁定音区打开，需要调用AIFespCarEngine#setDriveMode(4,3) 表示自由组合模式，只处理主驾和副驾音频 如果锁定音区关闭、，需要调用AIFespCarEngine#setDriveMode(3,3) 表示全车模式,但是只混音主驾和副驾音频抛出 4. 主驾按键，主动拉起唤醒的同时需要主动调用一次AIFespCarEngine#setDoaManually，传值1。lite内部机制：只有在定位模式时才有效果。
