JSON Api and Progressive webui

[barchiesi]

Hi everyone! I've been working on the web user interface a bit and have gathered all changes in a patchset contained in the barchiesi/ats-mini fork. As of now I have:

• Static web pages generation in firmware sources (example https://github.com/esp32-si4732/ats-mini/blob/main/ats-mini/Network.cpp#L610) replaced by a dedicated npm project;
• JSON Api for retrieving radio status or memories and updating configs (OpenAPI 3.0 spec here);
• All radio information is available in the status web page and automatically refreshes;
• All settings can be changed in the config web page;

I added the JSON Api so the radio can be potentially monitored and controlled by anything that speaks JSON, like home automation systems or small widgets many DEs allow creating. I have a "very-custom-hacky universal remote control" and now I can control the ATS Mini radio seamlessly with my other devices.

I believe decoupling the web pages from the c/cpp sources and generating them via a proper npm project vastly simplifies development of that user interface as changes can be tested without flashing firmware to the device. It lowers the barrier of entry for new developers that only know web frameworks/languages.

The above features can be checked out by flashing the binaries downloadable from the releases page of the GitHub fork. I am a user of the firmware in the esp32-si4732 repo so I will try to track the releases there and release the same versions with a d suffix to identify the web ui patchset.

In the future I will probably continue working on the following features which I believe are interesting:

• Adding memory items from the memory web page
• Exporting and importing of configs from a downloadable json file
• Switching memory stations from the webui
• Controlling radio options
• Redesign into a more captivating UI

I would love it if upstream accepted my changes, I'll try chunking them out in smaller progressive PRs so the review process is contained.

Test out the changes and let me know if you find any bugs!

Hi all, I released a new v2.28d version with the following changes compared to upstream v2.28:

• All radio information is available in the status web page and automatically refreshes every second;
• Volume and frequency can be changed from the web page;
• The memory web page automatically refreshes every 5 seconds;
• Memories can be tuned to from the web page by clicking the slot number;
• All settings can be changed in the config web page;
• JSON Api supporting all of the above (OpenAPI 3.0 spec here);
• Static web pages generation in firmware sources replaced by a dedicated npm project which simplifies development and lowers the barrier of entry for new developers;

Test out the changes and let me know if you find any bugs!
