## Description
Introduce an abstraction for handling cursors with multiple formats. The
abstraction handles:
- Trying formats in order of precedence during parsing.
- Serializing always to the "primary" format.
- Not offering a derived equality operator -- users need to define an
equality operator for their cursor type that handles normalization
between cursor types.
## Test plan
Updated the E2E test:
```
$ cargo nextest run -p sui-indexer-alt-e2e-tests --test graphql_transactions_query_tests
```
