Imports unification and other syntax changes

[FunFunFine]

There is a little inconsistency regarding imports in the library: while any other library (e.g. cats, cats-effect & tofu) import their syntax by import lib.syntax.something._ and import lib.syntax.all._, cats-helper does it in its own unique way by import com.evolutiongaming.SomethingHelper._.

It kind of slows down the adoption by newcomers, because they can easily miss that those syntax objects even exist, so I would like to propose to change this import scheme to be the same as in cats. WDYT?

Another thing I would like to discuss here (I don't think it is worth creating a separate issue for that) is the pollution by apply methods. One can easily find such code in cats-helper (e.g. Blocking, FromFuture):

trait Something[F[_]] {
  def apply(something: Thing): F[OtherThing]
}

object Something {
  def apply[F[_]: Something]: Something[F] = implicitly
}

Not only that it just doesn't work to call it like Something[F](thing) because of double apply and thing being treated as an explicitly passed instance, but IntelliJ IDEA often fails to find usages or asks if I want to go to the instance or to the method. In other words, it is inconvenient. So my proposal is to add alternative methods names with the possible deprecation of apply methods.

I could get this done, but I would like to see some discussion here. Are those proposals any good?

@FunFunFine not sure this does really makes a lot of sense, as comparing to cats/cats-effect - we don't have much to import hence not sure feature of being able to "selectively import something" is useful

As drawback - there is added maintenance and runtime cost of flexible solution

My proposal is more about syntax.all._ part. Currently there are seven different *Helper objects which need to be imported separately. Maybe we should allow them all to be imported with just one object then (e.g. import com.evolutiongaming.catshelper.syntax._)?

With upgrade to CE3 and changing package to com.evolution, this would be very welcome change (if one is afraid to add such nicer import in point release).

I've had numerous times, when I had to lookup which is the required import, thus having something common, very similar to Cats and Cats-Effect approach, would be very welcome usability improvement.

Nobody is going to remove the ability to have explicit single given imports.
