This array is indexed by rook advantage and minor piece advantage.
rook advantage is 4 + white rook equivalents - black rook equivalents
where a rook equivalent is number of rooks + 2 * number of queens.
minor piece advantage is 4 + white minors - black minors.
The classic bad trade case is two minors for a rook. If white trades
two minors for a rook, rook advantage is +5 and minor advantage is +2.
imbalance[5][2] gives a penalty of -42 for this trade.

First term is a character string explaining what the eval

Second term is the "type" of the value.

1 = scalar value.

3 = array[mg][side][64]. These values are displayed as 8x8
boards with white values at the bottom, and the ranks/files
labeled to make them easier to read.

6 = array[mg][side][8]
7 = array[mg][small#]
8 = array[n]
9 = btm/wtm two element array
Third term is the "size" of the scoring term, where 0 is a
scalar value, otherwise it is the actual number of elements in
an array of values.
Fourth term is a pointer to the data value(s).
