* refactor(datasource): migrate to class based datasource
A small experiment into what OOP/class based datasources might look like. Picked Cdnjs as it's the smallest & simplest.
With this approach we can share common logic, like error handling, rate limiting, etc. between different datasources, instead of having to reimplement it each time we write a new datasource. Currently there's nothing shared, as it's only 1 datasource, but the interesting stuff will come with the 2nd datasource
