Investigate and possibly add support for Scala 3 #14
Description
Description
Scala is clearly moving towards the next version and Figlet4s wants to be an up to date library.
Do a spike for to investigate the effort required to support Scala 3 and produce a PoC. Consider using 2.13 libraries for Scala 3 too.
If the PoC is succesfully and the effort required it not too big (i.e. a week for production ready), extend the PoC to full feature.
Figlet4s needs to also support Scala 2.12 and 2.13 at the moment of writing
