Re-implememented to use Deno instead of python for cleaner developpment

Should be compatible with cve-search data format.

Uses async generators in order to maximise the speed of the app while maintaining a clean implementation.

There is no use of redis here

-> Why do we want to do chunks of one month ?

That is easier to work with, and if a chunk fails that is easier to retry a smaller portion

• Implement the cpe match data feed
• Clean the implementation
• Implement differential update using the last date
• move to chain instead of pipe and using "on" / implem backpressure
