Quill integration

[daniel-shuy]

I have a suggestion to add a trait to automatically encode/decode EnumEntrys as Strings, using their entryName, when querying/inserting from/into a Database using Quill.

This is my current implementation:

import enumeratum.{Enum, EnumEntry}
import io.getquill.MappedEncoding

trait QuillEnum[A <: EnumEntry] {
  this: Enum[A] =>

  implicit lazy val enumEncoder: MappedEncoding[A, String] = MappedEncoding(_.entryName)

  implicit lazy val enumDecoder: MappedEncoding[String, A] = MappedEncoding(withName)
}

Sounds like a good idea :) A PR for adding said integration is welcome !
