Install this theme component

## Description

This component allows you to run code in codeblocks. This may not be applicable to every scenario, though, so not all code can be run.

This uses [OneCompiler](https://onecompiler.com) to embed code editors using iFrames. OneCompiler supports [many languages](https://onecompiler.com/#:~:text=Twitter-,Languages,-Java), but not all are supported in this Theme Component. For example, this does not support CSS frameworks, since only 1 codeblock ↔ 1 file.

## Settings

`default_file_name`: The filename of the file in the OneCompiler embedded editor. Defaults to `main`.

`show_language_switcher`: Show the language switcher to change the language of the embedded editor. Defaults to `false`.

`show_create_new_file_button`: Show the + button to add new files of the same language, or to add dependencies to the project, where applicable. Defaults to `true`.
