Initialising with a set of evaluated pairs (x0, y0)

Great AutoML tool. Thank you!

I like to scan a mesh of parameter combinations before HPO. How can I seed TPOT's GA/GP with these evaluations?

Is there an existing approach to this? Parameters for this are usually of the form,
```python
x0
list, list of lists or None
Initial input points.

y0
list, scalar or None
Evaluation of initial input points.
```
