Bye Scala Meta

[notxcain]

This PR removes scala.meta based macro annotation in favour of good ol' macros.

tl;dr
Replace this

import aecor.macros.boopickleWireProtocol

@boopickleWireProtocol
trait Algebra[F[_]] {}

with this

import aecor.macros.boopickle.BoopickleWireProtocol
import aecor.encoding.WireProtocol

trait Algebra[F[_]] {}

object Algebra {
  implicit def wireProtocol: WireProtocol[Algebra] = BoopickleWireProtocol.derive
}
