v2.129

Development has stopped on this project and no release has been made with all the latest stuff, making it a pain to obtain all of the parts (git clone reports errors and downloading manually also means having to download each submodule manually).

The repo has a few submodules linking to old commits. I've updated minmea to the latest version in the release download below (GPRS_C_SDK_V2129.zip). The repo still links to the original old commit. All of the other submodules have had tons of changes and will probably break something if they're updated.

• iotkit-embedded: Too many changes
• cJSON: Some new commits, could do with being updated, but the version included in the SDK has had some things done to it for the A9 modules (currently v1.7.7)
• minmea: Some new commits, latest is in release download (https://github.com/kosma/minmea/tree/ae4dd9442a9041345d5ef108f062e7e4ec6954f2)
• lvgl: Too many changes
