General category database. Conceptually this is a sorted array of ascending, non-overlapping inclusive codepoint ranges, with a GeneralCategory attached to each of them. Note that NotAssigned should not be present in this array.

Internally every element is packed into Word64, for the least significant bits:

• 0-23 bits represent the low codepoint range (inclusive)
• 24-47 bits represent the high codepoint range (inclusive)
• 47-63 bits represent general category values consistent to GeneralCategory's Enum instance.
