More features, minor bug fixes

1. Improved Regex

• Throughout my use, some job's exp criteria escaped through the regex. I found out some HRs like to put years as yrs
• The new regex checks for that

2. Improved text extraction

• Some bad words that I put such as "contractor" escaped cus the normally extracted description has leading and trailing white spaces
• new function to polish the extracted text while also maintaining its structure

3. Check to unfollow company at the end

• Added a check to unfollow company before submitting the application
• Prevents clutter and unnecessary posts from popping up in the feed

4. Work style preference

• Added a check to only apply to jobs that match your preference (remote | on-site | hybrid)
• Empty field will ignore the checking
