Fixes library and compilation warnings, defaults to Scala 2.13

updates Circe to 0.13.0 (only for Scala 2.12 and 2.12)
downgrades typesafe config to 1.3.3, since this is the version that Akka HTTP uses
excludes scala-library from dependencies
upgrades Akka HTTP to 10.1.12
for Scala 2.13 dsql uses StringContext.checkLengths and StringContext.processEscapes, since sc.checkLengths and StringContext.treatEscapes are deprecated.
default Scala version is now 2.13

For Scala 2.12 and 2.13 there aren't any incompatibilities among library dependencies. For 2.11 there are minor info messages for scala-reflect and jawn-parser:

In Scala 2.13 Either is right-biased, therefore .right is deprecated:

[warn] src/main/scala/ing/wbaa/druid/client/DruidClient.scala:155:52: method right in class Either is deprecated (since 2.13.0): Either is now right-biased, use methods directly on Either
[warn]               decode[List[DruidScanResults]](json).right
[warn]                                                    ^

To overcome this issue, I've added Scala-specific version of a helper function in ing.wbaa.druid.client.CirceDecoders that performs the desired map operation.

Specifically in Scala 2.11:

import io.circe.java8.time._

trait CirceDecoders extends JavaTimeDecoders {

  protected def mapRightProjection[L, R, R1](either: Either[L,R])(f: R => R1): Either[L,R1] = either match {
    case Right(value) => Right(f(value))
    case _ => either.asInstanceOf[Either[L, R1]]
  }

}

Similarly in Scala 2.12:

trait CirceDecoders {

  protected def mapRightProjection[L, R, R1](either: Either[L,R])(f: R => R1): Either[L,R1] = either match {
    case Right(value) => Right(f(value))
    case _ => either.asInstanceOf[Either[L, R1]]
  }

}

While in Scala 2.13 is simply:

trait CirceDecoders {

  protected def mapRightProjection[L, R, R1](either: Either[L,R])(f: R => R1): Either[L,R1] = either.map(f(_))

}
