Support for more ODS output types

[Cleester4]

Is your feature request related to a problem? Please describe.
Currently. the extension appears to support only HTML5 output from SAS. Users have need to generate all kinds of output types, including PDF, Word, Excel, and Powerpoint output.

Describe the solution you'd like
There should be a way to enable these output types in the extension, even if the extension does not provide a way to display them directly. However, there should be simple way for the user to download the output files, as they have in SAS Studio.

Additional context

• The "ods all close;" should ALWAYS be submitted by the extension after the user's code has been submitted. This ensures that all ODS output types (including HTML5) have an opportunity to close properly. HTML and HTML5 can technically be displayed without it, but the other output types will not complete without it. It's always best to submit that statement.
• There is already a separate ticket for having the extension select the correct ODS style based on the extension's theme. For the Microsoft Office output types (Word, Excel, and Powerpoint), there are specialized version of those styles that should be selected. For example, if you are using the "dark" theme, you would use the "ignite" style for HTML5 and PDF output, but you would use "WordIgnite", "ExcelIgnite", and "PowerPointIgnite", respectively.

Please include old fashioned text output (.lst) as an output format as well. Obviously this would be easy to display, and often text output is easier to work with than HTML.
