+`TableId.toHex()` now truncates name/namespace to 16 bytes each, to properly fit into a `bytes32` hex string.
+
+Also adds a few utils we'll need in the indexer:
+
+- `bigIntMin` is similar to `Math.min` but for `bigint`s
+- `bigIntMax` is similar to `Math.max` but for `bigint`s
+- `bigIntSort` for sorting an array of `bigint`s
+- `chunk` to split an array into chunks
+- `wait` returns a `Promise` that resolves after specified number of milliseconds
