Hackernews integration

[Mira-Alf]

Changes

• Changed index.js to call hackernews generation if -h option is provided. Tested with this: node . -h 25288188
• Added new templates for hackernews
• Made changes only for pdf - will update this branch for epub generation in the same branch tomorrow
• Also I have utilized @tr0mbl3y's code for most of the integration, but put it in a separate folder - so his folders need to be deleted - since his json structure was not compatible with our current structures

Some testing cases I tested the code with to view the output: node . -h 25301437 I have attached a sample pdf that I generated to get a quick view of what I have. I am not happy with the formatting - that needs to be cleaned up. brandrick-Netscape-a-Dec-4-2020.pdf
