Support the BMFONT format

[LavenderTheGreat]

Might work on a pull request for this, but BMFONT is one of multiple standards for these kinds of fonts. Developed by AngelCode in the early 2000s, they commonly come in the ini-like format, since the binary format is much more unreliable. An example can be generated from either my BMFONT creator (similar style to this) at itch.io, the official tool from AngelCode or using this tool. The extension is usually .fnt.

They're supported by Unity with an extension, Godot by default and same with frameworks like LOVE.

A slight, much more minor appendix is the format .PCF used by Linux terminals, which while far far less common (Only used in some terminals for early X systems and in some more technical programs), has some good typefaces.
