This PR adds the Xorigin AiPi-Lite board, allowing it to run v2 of xiazhi-esp32 rather than v1 which it seems to ship with.

1. Use "CONFIG_SR_WN_WN9_NIHAOXIAOZHI_TTS=n" to disable the default Chinese wake word in config_en.json
2. Choose a different build name in config_en.json like aipi-lite-en. The build name is a firmware identifier used in OTA update.
3. Is this PR official or not?

Thanks for the heads up, will do.

2. Choose a different build name in config_en.json like aipi-lite-en. The build name is a firmware identifier used in OTA update.

Good to know. I'm going to change it to aipi-lite_en for consistency unless you prefer aipi-lite-en.

3. Is this PR official or not?

This PR, and myself, have no affiliation with Xorigin. I recently purchased one of these devices in the hopes of using it for my own projects after figuring out the pin mappings and your project was a big help in testing and validating those.

Thank you for taking the time to review my PR, I'll make sure to incorporate your suggestions.
