Preview: new font designed for Keyball

[koron]

I designed a new font for Keyball OLED.
Please see the sample image. The top one is the current one, the bottom one is the new one.

The problem with current font is that the line spacing is so close that they sometimes appear stuck together.
This is not suitable for Keyball's OLED display, which displays information grouped on a line-by-line basis.

To solve this problem, I created a new font with increased line spacing.
The current font were designed using a full 5x7.
The new font has many glyphs that fit within a 5x6 area.
Also, glyphs such as "y" and "g" that protrude from the baseline are kept within 5x7, with a 1-dot gap between them and the next line.
