Default background color should be "No Fill"

[jnothman]

Currently the background colour for cells defaults to white, per:

StyleFrame/styleframe/styler.py

Line 94 in 9a9ab57

self.bg_color = get_color_from_string(bg_color, default_color=utils.colors.white)

I think the default background colour should be No Fill.

This is important when, for instance, the user adds a Table to the spreadsheet. Its banding won't appear if the cell background is white.

Maybe related to #42.

I think this is not about the default value of Styler.bg_color, but of Styler.fill_patern_type, right?

Probably Styler.fill_patern_type; I'm no expert on openxml
