Implemented arb finder
node scripts asynch

Sorted the performance issues by figuring out how to call the scraper
scripts asynch. Only implemented for OC fixtures just now.
BF Fixture site update

BF updated their DOM on the competitions url. The entire fixture is now
in the .home-team element.
Refactor

Removed hard-coded values.
BF Fixtures async
Added method
BF match odds async scraping
Finished async scraping

Seen a few bugs where the scripts didn't appear to run until completion.
And my machine crashed a few times, suspect I spun up too many processes
but I also need to look into my db access calls as I suspect there might
be a bit of locking.
