Make pipeline less verbose

[KarenJewell]

Is your feature request related to a problem? Please describe. Current pipeline is extremely verbose as all the scrapers are doing their own thing. It becomes a bit too much to read when debugging.

Describe the solution you'd like Options:

1. Switch of all individual print statements
2. standardise messages at main() level
3. add parameter to switch on/off verbosity

Describe alternatives you've considered rip it all out and rebuild as modules.

Additional context None.

I did introduce Loguru when I worked on main.py last but didn't really get round to applying it to any other scripts
