see if it's possible to upgrade to Scala 2.13 and then we can cross compile

[outkaj]

for 2.12 and 2.13

[outkaj]

I played around with this recently. Not quite there yet, getting compile errors on our custom types such as:

found   : org.adridadou.openlaw.OpenlawString
[error]  required: String
[error]         case Some(value:OpenlawString) => cast(value, executionResult)

and not quite clear why to me. Seems lower priority for now.

What file/line is that? Might be a change in implicit resolution that's affecting the type class.

@craigwblake-openlaw I think @adridadou has done some work on this in a branch which is more recent than what I've done.

Seems like it's not a super high priority atm though given instability of some of other related deps
