Implement interpretation of Read(min, max) instruction

[sergei-shabanau]

1. I think it should be

Read(min: Int, max: Int)

in CodecVM

2. The use case

case Read(min, max) =>

to be implemented in def interpret where min and max are not both 1.

You won't have such instruction in JVM. It may be useful to compile to just jumps (loops + conditions) and state.

True. We have defined

case class Read(min: Option[Int], max: Option[Int])  extends CodecVM

but if it becomes just

case object Read

then this issue is not needed.
