Add a parser for Scilab language

[vincentcouvert]

Hi all,
Please find below information related to the development of a Scilab parser in Rouge.
Best regards.

The name of the language
Scilab: https://www.scilab.org/
Online help: https://help.scilab.org/

Implementation in other libraries
Pygments: https://pygments.org/docs/lexers/#pygments.lexers.matlab.ScilabLexer
Chroma: https://github.com/alecthomas/chroma/blob/master/lexers/embedded/scilab.xml
Highlight: https://github.com/highlightjs/highlight.js/blob/main/src/languages/scilab.js

Additional context
GitLab uses Rouge to detect language used in files and GitLab is now the official Scilab development platform.
Having this feature in Rouge would simplify the reading of Scilab code in repository, issues, wiki, ...

{% highlight ruby linenos %}
def foo
  puts 'foo'
end
{% endhighlight %}

@y377 what do you mean?

[y377]

Sorry, I just want to try code highlighting, it turns out that GitHub does not support this way of defining code blocks

Do you support this way of defining code blocks? Because it is very convenient to write in the markdown editor, because it is suitable for non-code developers to use!

@y377 I think your question is not related to this issue (which is about Scilab language support).
