bokeh support

Not sure how I would do this. The following code opens a graph in the browser:

Specifically "file:///C:/dev/AREPL-vscode/node_modules/arepl-backend/python/python_evaluator.html"

```python
from bokeh.plotting import figure, output_file, show

x = [1,2,3,4,3]
y = [6,7,2,4,5]

#output_file("lines.html")

p = figure(title="simple line example", x_axis_label='x', y_axis_label='y')

p.line(x, y, legend="Temp.", line_width=2)

show(p)
```

So it should be possible to render it in arepl instead.... but not sure how I would do that :/
