.NET 7 introduced Int128 / UInt128.
How to implement those formatters?
Option 1 - Bin Array
BigIntegerFormatter serializes BigInteger as byte[].
This option seems most performant because sizeof(Int128) is always 16.
Option 2 - Msgpack Way?
There are 2 proposals for big integer/float.
Both proposals are denied by messagepack author.
This option seems not good because other messagepack implementations do not adopt this option.
Option 3 - Original Ext
Original extension.
Option 4 - Do Nothing
Do not support Int128/UInt128 officially.
There was no issue about these types and no one suffers. (Except #1593, but this issue opener seems not in trouble.)
