Scala 2.13 support

[ennru]

I'm not sure which dependencies are missing, but 2.13 things are showing up now...

@hseeberger please merge @scala-steward updates for jsoniter-scala, it supports Scala 2.13-RC1 already:

PR: #281

upickle dropped support for 2.11 when it introduced support for 2.13 in 0.7.5: https://mvnrepository.com/artifact/com.lihaoyi/upickle

@hseeberger are you OK with dropping support for 2.11 when 2.13 is added?

[hseeberger]

@2m It is not OK to drop 2.11, it is a MUST! ;-)
Couple of days ago I already looked into bumping the Scala version to 2.13, but some libraries like Circe had not yet been there.

[plokhotnyuk]

Is any option to release selected modules for those libraries that were already released for Scala 2.13?

@plokhotnyuk that is indeed an option, let's do it.
