"chisel-iotesters" -> "1.4.1+" in build.sbt breaks Vec code (which is also in your solutions)

[FrancescoTerrosi]

Hello, I discovered chisel and its ecosystem (rocketchip, chipyard etc.) recently and I'm playing around with the various tutorials I found.

This is the error i get:

I was confused at first because I started from the Chisel Learning Journey and my code worked there. hence, i tried to run your provided solutions with
run-solution.sh all
and I kept getting the error above. Changing the chisel-iotesters from version 1.4.1.+ to version 1.2.+ fixed this issue, but the sensation of weird workaround pervades me.
