- EnumVals can now have an optional ty arg which the resulting enum can
use to show a type (ie MyType::Integer would be MyType::Integer(i64))
- implementing NumericUnion type, which om2 relies on
- importing Decimal from rust_decimal to support NumericUnion
- adding /// ID: <some id> doc comments for enums and structs (not
fields, would be too cluttered tbh)
- updating docs to point to the correct places
