Font Detection

[maeriil]

The font detection module does not currently work as intended.

The purpose of the module is to be able to detect the font and font size of the texts in the image. It is almost nearly impossible to detect font style so fixing this is not a priority currently.

Currently, the module is not calculating the original font size correctly. The algorithm works as follows currently:

1. Set left = MINIMUM_FONT_SIZE * scale, right = MAXIMUM_FONT_SIZE * scale
2. Binary search the right font size using the comparator is_font_size_small and is_font_size_big.
3. Return the found font_size

However, the issue lies inside is_font_size_small and is_font_size_big which needs to be further investigated and fixed asap.
