Instead of using submodules create a script that will make a shallow git clone of the dependency repos: 1. ulab 2. micropython 3. tflite-micro-esp-examples 4. tflite-micro (for non esp32 boards) Pin the versions to the latest releases of each dependency. ulab: 6.0.12 micropython: master esp32-tflite: v1.0.0 tflite-micro: <undefined> tflite-micro doesn't tag releases so its undefined to be the latest commit on the tip of the main branch. use latest micropython to get upgrade to idf 5.0.2
I copied the micropython board ESP32_GENERIC and replaced MICROLITE with minor adjustments to enable the microlite module and the name of the board.

Also update ci for building esp32 MICROLITE using the new build scripts.

Perhaps you might want also to update to the new camera API for Micropython. This works with the actual Micropython version. |

This is work in progress to change how tensorflow is built and linked into the microlite firmware. Instead of enumerating all of the source files I build the tensorflow part with esp_nn for accelerated ops directly as an esp-idf component.
It also upgrades the microlite module to work with latest micropython master (>1.20.0).
The submodules are deleted. Instead a new scripts/build.sh has been created. It has two functions:
I've run through the steps manually and was able to build firmware for the MICROLITE board and flash it an run the microspeech demo.
The second commit contains changes from @uraich for upgrading microlite to use the new module registration macros.
The next steps are to change the ci builds to use the new build script, upgrade the other board configurations and ensure the unix and rp2 builds still work properly.
