Bookxel Capital Upgrade

 This font is the most popular among my projects and people download it a bunch, so I decided to take a day and refine the font.  The capital letters were addressed and have decreased in height. This makes the gap between upper-case and lower-case letters less jarring. The numbers were also updated in their heights. 

 The lower-cased characters were touched upon lightly to improve their negative space and increase legibility and compose-ability. For example, the dots on 'i' and 'j' have an extra white-space now. The 'g' also takes one more bottom space to give it its bottom curve without interfering with its top part. The old font is still included in the package for backwards compatibility, and it can be used to see the changes made in the new font.  

 The font is also now packaged as 1 zip, since the assets are so small. This actually decreased the total size significantly. And it is also simpler.

 Since the last update also Godot Engine 4 has been released, while the font has only Godot 3 preset.  So the project now also included presets for the newest Godot version.
