From 8d7f27d9a0b61d3694a62f3e54be885d8073f02b Mon Sep 17 00:00:00 2001
From: mrb0nk500 <b0nk@b0nk.xyz>
Date: Sat, 13 Feb 2021 13:59:48 -0500
Subject: - Reverted back one commit before the previous commit.

  This is because the previous commit actually created
  a bug, rather than fixing one.

- Added JMP, and JSR to the ortho extension, and
  implemented them both in the assembler, and
  emulator.
