feat: support maxSize in PbjGrpcClient

[anthony-swirldslabs]

Description:
Adding support for configuring a custom maxSize for the PBJ GRPC Client so that it's able to receive messages larger than 2MB (per the current Codec.DEFAULT_MAX_SIZE.)

Related issue(s):

Fixes #748

Notes for reviewer:
A new integration test is added to verify the behavior. W/o the fix, or w/o specifying the maxSize in the client config, the test fails with a ParseException about the size of the payload exceeding the limit.

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)
