Lots of changes (#70)

Image extraction and conversion to formats 

Multi parallel file execution for all forms so you can input multiple files quickly 

Any file at all pdf using libreoffice, super powerful
Sadly makes docker image larger but worth it 

OCR PDF using ocr my pdf
Works awesomely for adding text to a image

Improved compression using ocr my pdf app

Settings page with custom download options such as 
- open in same window
- open in new window
- download
- download as zip

Update detection in settings page it should show notification if there is a update (very hidden)

UI cleanups

Add other image formats to PDF to Image

Various fies to icons, and pdf.js usage

+# OCR Language Packs and Setup
+
+This document provides instructions on how to add additional language packs for the OCR tab in Stirling-PDF, both inside and outside of Docker.
+
+## How does the OCR Work
+Stirling-PDF uses OCRmyPDF which in turn uses tesseract for its text recognition.
+All credit goes to them for this awesome work! 
+
+## Language Packs
+
+Tesseract OCR supports a variety of languages. You can find additional language packs in the Tesseract GitHub repositories:
+
+- [tessdata_fast](https://github.com/tesseract-ocr/tessdata_fast): These language packs are smaller and faster to load, but may provide lower recognition accuracy.
+- [tessdata](https://github.com/tesseract-ocr/tessdata): These language packs are larger and provide better recognition accuracy, but may take longer to load.
+
+Depending on your requirements, you can choose the appropriate language pack for your use case. By default Stirling-PDF uses the tessdata_fast eng but this can be replaced.
+
+### Installing Language Packs
+
+1. Download the desired language pack(s) by selecting the `.traineddata` file(s) for the language(s) you need.
+2. Place the `.traineddata` files in the Tesseract tessdata directory: `/usr/share/tesseract-ocr/4.00/tessdata`
+
+#### Docker
+
+If you are using Docker, you need to expose the Tesseract tessdata directory as a volume in order to use the additional language packs. 
+#### Docker Compose
+Modify your `docker-compose.yml` file to include the following volume configuration:
+
+
+```yaml
+services:
+  your_service_name:
+    image: your_docker_image_name
+    volumes:
+      - /usr/share/tesseract-ocr/4.00/tessdata:/location/of/trainingData
+```
+
+
+#### Docker run
+Add the following to your existing docker run command
+```bash
+-v /usr/share/tesseract-ocr/4.00/tessdata:/location/of/trainingData
+```
+
+#### Non-Docker
+If you are not using Docker, you need to install the OCR components, including the ocrmypdf app.
+You can see [OCRmyPDF install guide](https://ocrmypdf.readthedocs.io/en/latest/installation.html)
+
+
