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.

+#### Consider using the Typelines module instead of this one.
+
+#### 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, unindented, before the card style section:
+include file: /magic-modules.mse-include/indicators/card_fields
+#### For DFC or TFC templates, instead override the faces_coordinates function, and use:
+include file: /magic-modules.mse-include/indicators/card_fields_dfc
+include file: /magic-modules.mse-include/indicators/card_fields_tfc

+#### Customization
+#### Optionally, you can define which face of the card the color indicator should snap to,
+#### by defining the following function in the init script:
+typeline_face_1 := { 1 }
+
+#### You can also adjust global alignment by defining the following functions, again in the init script,
+#### which must return an int corresponding to the number of pixels you want to shift the color indicator by:
+
+#### To shift the color indicator up/down:
+indicator_offset_top_1 := { 0 }
+
+#### To shift the color indicator left/right:
+indicator_offset_left_1 := { 0 }
+
+#### To increase/decrease the width and height of the color indicator:
+indicator_offset_size_1 := { 0 }
+
+#### For DFC or TFC templates, use:
+indicator_offset_top_2 := { 0 }
+indicator_offset_left_2 := { 0 }
+indicator_offset_size_2 := { 0 }
+indicator_offset_top_3 := { 0 }
+indicator_offset_left_3 := { 0 }
+indicator_offset_size_3 := { 0 }
