FEAT: Rework to improve performance

[LiquidCats]

Summary

The Pull Request refactors and reorganizes the jsonrpc package by modularizing code into separate files for better maintainability, improves HTTP client configuration, and updates dependencies to newer versions. Additionally, it introduces benchmarks and more extensive test coverage for new functionality.

Main changes:

• Refactored client.go: Removed JSON-RPC-specific logic, moved it to new files (data.go, executor.go).
• Added data.go file: Encapsulates JSON-RPC-specific data structures and methods.
• Added executor.go file: Handles JSON-RPC request execution, with configurable options for HTTP requests and clients.
• Improved test coverage:
  • Added tests for the newly introduced data.go and executor.go.
  • Removed outdated tests from client_test.go and replaced them with improved tests in relevant new files.
  • Added benchmarks and goroutine-based performance tests.
• GitHub Actions workflow update (test.yml):
  • Updated dependencies for actions/checkout and actions/setup-go.
  • Added new bench step to run benchmarks separately.
• Updated Go module dependencies (go.mod and go.sum):
  • Updated several existing dependencies to newer versions.
  • Replaced github.com/go-faster/errors with github.com/rotisserie/eris.

This PR improves the structure, maintainability, and reliability of the jsonrpc package while keeping backward compatibility.
