Investigate table compression

[lemire]

We can save about 37KB of tables, while possibly improving the performance.

Also Unicode 16.0 has come and has some updates on normalization algorithms and some new code points that change the tables (most likely).

And, also, I remember that you had NFKC and NFKD composition and decomposition code points in your tables which is not being used, but I might be remembering another repo!

These are in your slow path algorithms mostly, so I'm aware they're not a priority.

It's about 110 KiB save:

• IDNA Mapping tables: yours 84.47 KiB -> mine 45.03 KiB
• Decomposition tables: yours 73.43 -> mine 41 KiB
• Composition tables: yours 45.23 KiB -> mine 14 KiB
• CCC tables: yours 21 KiB -> mine 13 KiB

So, I have saved 224.13 - 113.03 ~= 111 KiB.
