This task expands the virtual machine defined in day 2 adding jumps, conditionals, inputs, and outputs.

This solution works with the following passes:

1. Parse input text file into a list of numbers
2. Execute op codes to extract the input/output "effects"
3. Evaluate the effect as a function from a list of inputs to list of outputs
4. Apply the function to a single input and find the last output.

>>> intcodeToList [3,12,6,12,15,1,13,14,13,4,13,99,-1,0,1,9] <$> [[0],[10]]
[[0],[1]]

>>> intcodeToList [3,3,1105,-1,9,1101,0,0,12,4,12,99,1] <$> [[0],[10]]
[[0],[1]]

>>> :{
>>> intcodeToList
>>> [3,21,1008,21,8,20,1005,20,22,107,8,21,20,1006,20,31,
>>> 1106,0,36,98,0,0,1002,21,125,20,4,20,1105,1,46,104,
>>> 999,1105,1,46,1101,1000,1,20,4,20,1105,1,46,98,99]
>>> <$> [[7],[8],[9]]
>>> :}
[[999],[1000],[1001]]
