Not working with arduino-cli on MacOS

[Curs3W4ll]

Describe the bug I tried using this plugin, using arduino-cli.

System information

• OS: mac (Sonoma, 14.5 (23F79))
• Vim: NVIM v0.11.0-dev-164+g3a1515bfe
• Arduino: Not installed (not specified explicitely in the doc, should I?)
• CLI version: arduino-cli Version: 0.35.3 Commit: 95cfd654 Date: 2024-02-19T13:15:51Z
• ArduinoInfo:

  Error detected while processing function arduino#GetInfo[1]..arduino#InitializeConfig[62]..ar
  duino#ReloadBoards:
  line   37:
  Could not find any boards.txt or programmers.txt files. Please set g:arduino_dir and/or g:ard
  uino_home_dir (see help for details)
  Board         : arduino:avr:uno
  Programmer    :
  Port          : /dev/tty.usbmodem1101
  Baud rate     : 9600
  Hardware dirs : None
  Verify command: arduino-cli compile -b arduino:avr:uno -p /dev/tty.usbmodem1101 --build-path
  "/private/tmp/test/build" -v "/private/tmp/test/test.ino"

To Reproduce Steps to reproduce the behavior:

1. Install only arduino-cli only
2. Install the plugin
3. Open a .ino file
4. See this error message

Expected behavior The plugin should work without any error?

Working command This is not an issue with arduino-cli, so I don't think this is relevant?

You shouldn't need an Arduino IDE installation for this to work, but the last time I tested it (several years at this point), arduino-cli had some bugs with listing board details

https://github.com/stevearc/vim-arduino/blob/2ded67cdf09bb07c4805d9e93d478095ed3d8606/autoload/arduino.vim#L110-L112

I am very far away from a computer that has arduino-cli set up and won't be able to test this myself. If you're interested you could try checking if the commands work now, and refactor the logic to rely on that instead. You could even try just making it gracefully fall back to using the arduino-cli; it's not like that would be worse than failing entirely.
