The main idea is to:

Given a list of Blob IDs, use a new endpoint to check for their existence
Iterate the Blobs list, upload only non-existent ones, and skip the rest

To achieve this, we can use this new GraphQL endpoint introduced in v0.34.0:

feat: graphql endpoint to fetch the blob byte code by its blob ID fuel-core#2096

Important:

Perform a single request with multiple GQL queries, one per Blob ID (avoids unnecessary roundtrips)
Make sure not to ask for the Blob bytecode in the query (avoids bloating server response)
