feat(ts): add Starknet data types

[xJonathanLEI]

This is the first of a series of PRs for adding Starknet support into graph-tooling, following the addition of Starknet support in graph-node. This first PR adds support on the ts side, which is essentially mapped from the corresponding parts in graph-node.

This PR also adds a type Felt. This type is added because unlike in Ethereum where bytes and integers and distinct types (and hence have different representations in ABI), in Starknet the type felt252 (or felt in Cairo Zero) is often used to represent both addresses and numbers. If we simply use Bytes for it, users might find it difficult to convert them into BigInt, as BigInt only takes little-endian arrays.

Once this gets merged, I will submit follow-up PRs that add Starknet subgraph initialization, codegen, and compilation support on the cli side. I figured following the "ts first then cli" approach should be easier.

so on the PR that I merged CI was green #1527 .... investigating issue more seems like I have to pin pnpm version #1528

[xJonathanLEI]

Yeah saw the green CI on PR too.. weird that it fails on main.

[saihaj]

ok @xJonathanLEI if you can merge main to this branch it should work 🤞🏼

[xJonathanLEI]

Rebased. Let's see if it works :)
