Update Unifont from v15.0.01 to v15.0.03

https://github.com/multitheftauto/unifont/releases/tag/v15.0.03

This also includes the v15.0.02 update.

## 21 May 2023 (Unifont 15.0.03)
- Minor update with some Makefile modifications. The one notable change is that unifont_all.hex is now installed in the .../share/unifont directory, at the request of the gaming community. This hex file spans all Unicode planes. The unifont_jp.hex file now also includes the Plane 3 glyphs by Ming Fan.

## 20 May 2023 (Unifont 15.0.02)
- **N.B.: This is expected to be the last Unifont release to build TrueType fonts by default, replaced by OpenType versions. TrueType fonts will still be able to be built manually using the command "make truetype" inside the font directory. The OpenType fonts are more compact than the legacy TrueType versions.**
- Added Plane 2 Chinese ideographs drawn by 湖 远星 to the basic Unifont font files for coverage of the General Standard Chinese Characters set. Also added Plane 3 glyphs drawn by Ming Fan, with permission.
- Updated Fullwidth CJK characters in the range U+FF00..U+FFEF so they no longer appear boldface, using glyphs from Wen Quan Yi with some modifications. Thanks to 何志翔 (He Zhixiang) for checking their alignment and suggesting improvements.
- Minor updates to other individual glyphs, notably a much improved skunk glyph (U+1F9A8) from Curtis Mackie. See the ChangeLog file in the release tar file for full details.
