Align API with cats/fs2

[guersam]

There have been several API changes in cats, cats-effect and fs2. As we are still in milestone phase, it'd be helpful for newcomers to keep the names as consistent as possible with our dependencies.

Things to consider (maybe incomplete):

• Update#fail -> Update#raiseError (MonadError#raiseError)
• Update(0)#run -> Update(0)#compile (Stream#compile): might be confusing because Stream#compile needs a consequent combinator unlike deprecated Stream#run
• deprecate Query(0)#process in favor of Query(0)#stream
• {Kernel, Composite}#zip -> {Kernel, Composite}#product (Semigroupal#product) or Kernel.product -> Kernel.zip

Alternative to Update#compile could be

• Update#run -> Update#single
• Update#updateMany -> Update#many
