This file has a few functions that are helpful for testing such as creating dummy maps and faking interrupts

Aim is to create an 8x8 table that looks like the below:
 MAP
______________________________________________
|100|| 78 | 88 | 92 | 95 | 97 |101 |107 |110 |
| 88|| 58 | 88 | 75 | 63 | 50 | 38 | 25 | 13 | 
| 75|| 45 | 88 | 75 | 63 | 50 | 38 | 25 | 13 | 
| 63|| 35 | 88 | 75 | 63 | 50 | 38 | 25 | 13 | 
| 50|| 28 | 88 | 75 | 63 | 50 | 38 | 25 | 13 | 
| 38|| 22 | 23 | 75 | 63 | 50 | 38 | 25 | 13 |  
| 25|| 17 | 21 | 75 | 63 | 50 | 38 | 25 | 13 | 
| 13|| 15 | 20 | 25 | 63 | 50 | 38 | 25 | 13 | 
|   || 500|1500|2000|2500|3000|4000|5000|6000| RPM

This is not really a realistic 8x8 VE vs RPM 2D map, but it's enough for testing
Here is a run through of how the interpolation would flow:
Pass in:
x = 1000
y = 20

yMax = 13
yMin = 25

xMax = 1500
xMin = 500

A 17
B 21
C 15
D 20
p (1000 - 500) / (1500 - 500) = 1/2 = 0.5
q (20 - 13) / (25 - 13) = 7/12 = 0.583
m (1 - 0.5) * (1 - 0.583) = 0.2083
n 0.5 * (1 - 0.583) = 0.2083
o (1 - 0.5) * 0.583 = 0.29166
r (0.5 * 0.583) = 0.29166

VE = ( (17 * 0.2083) + (21 * 0.2083) + (15 * 0.9166) + (20 * 0.29166) ) = 18.125
