How it works

1. When user starts the program, we get all of the user's VSCode themes from the ~/.vscode/extensions folder.
2. We start a goroutine for each extension folder, which processes an extension (by reading and unmarshalling file) and sends its themes through a channel.
3. The main goroutine collects themes from the theme channel and appends them to the allThemes slice.
4. we display the themes to the user in a list from bubbletea's library, just for aesthetic purposes (vsctheme_picker.go)
5. If the user-selected theme does not have a themeType set, we ask the user to select one either light or dark. (theme_type_picker.go)
6. After getting the file path of the selected theme, we convert it to an iTerm theme using the convertTheme function (converter.go)
   • read theme file
   • removes comments and trailing commas or unmarshalling errors will occur
   • unmarshal the cleaned file
   • iterate through ANSI color mappings and retrive corresponding color from vscode theme + add fallback colors if missing
   • convert hex color to RGBA (iterm uses RGBA)
   • generate iTerm theme XML
