This PR is a major cleanup (sorry!). It solves the following issues:

• cargo fmt
• app and host folders' copy-paste from the rustzx app removed
• Requirements on SPI RAM removed
• More LED boards supported

What would be the major next steps if this emulator is to work properly?

• Most important is to optimize the emulator itself. I've configured it to run with 60 frames full-speed without interruption, and the result is that these 60 frames take ~ 8.5 seconds to render so we get ~ 7fps, while we should get 30-50fps to have a chance for a smooth playback (note that the SPI/display speed is not a major contributor - it is the emulator itself; even if you comment out the set_pixel code completely, it still runs with ~ 7fps)

So... either we optimize the emulator itself, or well, we stop here. :)

• Devcontainers now also work on GitHub Codespaces
  • We need to manually make the ports public, see instructions.
• Update rust-analyzer extension
• Use inputs arguments for tasks.json and launch.json
• Add web-flash and a script(flash.sh) to use from task in devcontainers
  • Also added default runner per target
• Add wokwi-server and a script(run-wokwi.sh) to use from task in devcontainers
  • There is also a default runner per target commented in .cargo/config.toml
  • Update build-rustzx.sh, run-wokwi.sh and flash.sh to acetp release or debug argument to select build profile
  • Updated documentation

Temporal branch for refactoring of the solution. Discovered several issues:

• embedded-svc must be fixed to older version, because of https://github.com/esp-rs/esp-idf-hal/issues/79
• when reference to WiFi goes out of scope, the WiFi is automatically disconnected
• tcp listener should be created inside new thread instead of passing from main thread to avoid problems with ownership

• Fix devcontainers files for VsCode
• Add task.json with task for building and running simulation
  • When building we use release profile but when running Wokwi simulator we use debug
• Add actboy168.tasks extension to show task buttons in the status bar
• Add GDB debugging support for Wokwi simulation
• Now using --merge argument of cargo-espflash to avoid having a logic for offsets when sharing the resulting binaries
• Updated README

Once the esp32-wokwi-gitpod-websocket-server PR (georgik/esp32-wokwi-gitpod-websocket-server/pull/1) gets merged, we need to update:

• https://github.com/SergioGasquez/rustzx-esp32/blob/main/.gitpod.Dockerfile#L43
• https://github.com/SergioGasquez/rustzx-esp32/blob/be91640506525e8774a728e301906ca8f0a18377/Containerfile#L51

In order to transfer those changes to other branches (targets) of the repo:

• [ ] Update cargo command in build-rustzx.sh and run-wokwi.sh
• [ ] Update ESP_BOARD and WOKWI_PROJECT_ID in run-wokwi.sh
• [ ] Update target in config.toml
• [ ] Update launch.json(both profiles) with the proper paths for gdbpath and executable
• [ ] Update terminal GDB command on README
