slot-nil vectors

Written only by the C# reference, tests/GameCult.Caching.Tests/SlotNilVectorTests.cs, with CULTCACHE_WRITE_VECTORS=1. Every other run reads this file and compares it byte for byte; a changed vector is a reviewed commit. Other runtimes decode it and are held to the same answers.

A record of five slots: S string, I int, B byte[], R a record of one string, L List of string.

• reads.msgpack: an array of [name, payload, accepted, rewritten]. payload (bin) is the record fed to the reference; accepted is whether it read; rewritten (bin) is what the reference writes after reading it, and empty when refused. It covers a nil in each kind of slot, a MessagePack str in the byte[] slot, a four-byte UTF-8 character (U+1F600) as the string slot and as a str in the byte[] slot, and records short of their last slots.
