[Feature]: Index more types of documents

[Fahube]

Problem Statement

Few common text document types aren’t read by DocFinder.

Proposed Solution

Add support to read:

• LibreOffice documents: odt, odp, odg
• Microsoft Office: doc, ppt, pptx
• Web documents: html
• Personalised extensions for raw text: for example the user wants to index srt, log files or any other type of raw text file. The user should be able to specify which optional extension(s) he wants to add.

Alternatives Considered

To convert manually each document in pdf.

Use Cases

When the user wants to index a different type of document.
