Rewrite Text Rendering (#10)

Rewrote text rendering to use font.Drawer instead of gg, which speeds up text rendering. Included in the updated text rendering is the addition of:
- Horizontal Alignment for text, options are Left, Right and Middle
- Overflow options, currently Wrap and Fade (actual fading is WIP, currently it just overflows off the image)
- Arbitrary text anchoring: an image.Point can be used to set an anchor point with text, and when combined with alignments, the alignments indicate the position of the text the anchor will be in, e.g., BOTTOM & RIGHT will put the anchor in the bottom right of the text, so all text will be up and left of it
