Add PlatformIO project setup, local libraries, and PCB Gerber files

- Add platformio.ini for ESP32 DevKit (Arduino framework, espressif32 6.10.0)
- Vendor ArduinoJson, MPU6050_tockn, SCServo, Simple_FOC, and WebSockets
  so a fresh clone builds without downloading dependencies
- Add .gitignore rules for PlatformIO/IDE build artifacts
- Add controller PCB Gerber and drill files

+## Minimal example of WebsocketClientOTA and Python server
+
+Take this as small example, how achieve OTA update on ESP8266 and ESP32.
+
+Python server was wrote from train so take it only as bare example.
+It's working, but it's not mean to run in production.
+
+
+### Usage:
+
+Start server:
+```bash
+cd python_ota_server
+python3 -m venv .venv
+source .venv/bin/activate
+pip3 install -r requirements.txt
+python3 main.py
+```
+
+Flash ESP with example sketch and start it.
+
+Change version inside example sketch to higher and compile it and save it to bin file.
+
+Rename it to `mydevice-1.0.1-esp8266.bin` and place it inside new folder firmware (server create it).
+
+When the ESP connect to server, it check if version flashed is equal to fw in firmware folder. If higher FW version is present,
+start the flash process.
