chore: bump eigensdk-go version

[entropidelic]

Bumps eigensdk-go from v0.1.6 to v0.1.9

The main changes were some APIs interfaces changes and structs names.

1. For instantiating a new BLS aggregation service, an additional parameter has to be passed, hashFunction, and the BLS aggregation service method ProcessNewSignature now receives TaskResponse (which is just a go interface{}, so it can be anything) as an argument instead of TaskResponseDigest, which was done before. The v0.1.9 version can be seen here and the v0.1.6 here. What we were sending in v0.1.6as the TaskResponseDigest was really just the batch merkle root, so to fullfil the API requirements, a dummy hash function that outputs its input is being passed as the hashFunction argument. This should not affect in anything and will just replicate the behavior we were having in v0.1.6.
2. The NewOperatorsInfoServiceInMemory function from the operatorsinfo module now receives a parameter logFilterQueryBlockRange, and if set to nil, a default value for that parameter is set. Check this lines and this comment.
3. Some structs such as AvsRegistryReader and AvsRegistryWriterchanged their names to ChainReader and ChainWriter.

Testing

To test the PR, just test normal flow, ideally with more than one operator

Tested it with 2 operators and worked as expected also code looks good

worked smoothly for me with 2 operators 👍
