Render colored bar vertically when width < height

[jul1u5]

Feature

Closes #44. I have implemented @0Karakurt0 suggestion which doesn't provide a rotation option but changes the orientation of the bar when the width of the bar is greater than its height.

Example:

$ tail -f $SWAYSOCK.wob | wob -W 64 -H 256

Implementation

In the wob_draw_percentage function, I wrapped the existing logic for drawing horizontal colored bar in an if condition and added a new branch for rendering the bar vertically. The logic for drawing the bar vertically is a bit different: I used a for loop instead of memcpy. Not sure about the performance implications of this.

Yay!)
