Reads a big endian encoded uint32 ID from the given byte slice.

DefaultIssuerMin specifies the default minimum ID value for newly issued IDs.

IDSz is the byte size of a symbol.ID (big endian) The tradeoff is between key bytes idle (wasted) in a massive db and exponentially more IDs available.

Issuer atomically issues unique IDs.

Table abstracts value-ID storage and two-way lookup.

ID is a persistent integer value associated with an immutable string or buffer value.
