card_fields rewrite and magic-modules.mse-include (#21)

Overhauls the card_fields file to allow for template designers more freedom in manipulating data.

Adds magic-modules.mse-include, a large scale include file for building templates in a standardized way. Applying this to existing frames will be coming in future updates.

+#### To use this include in a template, add the following in the template headers:
+depends on:
+	package:			magic-modules.mse-include
+	version:			2024-05-20
+
+#### Also add this among the styling field section
+#### (styling fields will appear in the order you place them).
+#### This will add a boolean to enable custom fonts, and four text
+#### options for customizing nameline, typeline, textbox, and pt fonts.
+include file: /magic-modules.mse-include/fonts/styling_fields

+#### You may also need to redefine the defaults in the style file:
+swap_fonts_name_default := [

+	size: {16},
+	color: {"black"},
+	vertical: {0},
