Placeholder: Leverage match opcode

## Problem

https://github.com/algorand/go-algorand/issues/4626 adds `match` opcode support. The story requests leveraging `match` in PyTeal + considering if it ought to be exposed to end users.

Consideration needed in these areas:
* Consider where usage is applicable. At a minimum, it feels like a good fit is leveraging `match` for ABI Router method invocation routing.
* Consider if/how to leverage + expose `pushints` and `pushbytess`.

For end user support, consider introduction of a switch-like statement.
