1.7.0

Bug fixes:

• Fixed a rare crash on programs with a large number of instructions
  had no effect.
• Fixed a memory issue where programs with a large number of cells
  (which were stored on the stack) were misoptimised and
  segfaulted. Cell storage is now on the heap.

Optimisations:

• Stripping symbols from the output binary can now be controlled with
  --strip.
• Re-added a multiply loop optimisation. This was removed in 1.5.0 due to
  soundness bugs.

Usability:

• Added a --version CLI argument.
