This change introduces new configuration, MaxReceiverSize & ICS20MemoLimit, in the relayer, path processor, and the global config. It updates the existing functions and methods to utilize this new configuration property for managing and validating receiver and memo sizes in IBC related tasks.

Added a new function WriteConfig in relayertest/system.go for testing. Also, updated method names in relayer.go to start with an uppercase letter for public visibility. Besides, upgraded Docker image version in localhost_client_test.go from v8.0.0-beta.1 to v8.0.0.

Created the Memo and Receiver Limit test within the interchain test suite. This test evaluates the functionality of IBC transfers with a memo field length exceeding configured limit, as well as receiver field exceeding the limit. It also evaluates a successful IBC transfer for completeness.

Adjusted the test case 'TestMemoAndReceiverLimit' to focus more on the functionality of sending transfers with a memo and receiver limit configured. This reduces the complexity of the test case, and it now focuses more closely on the actual purpose of the method. The general flow of the test has been maintained, but some unnecessary operations have been removed.

…ments

This commit removes various debug print statements from the code, making it cleaner and easier to read. Additionally, it updates the way the 'transfertypes.ModuleCdc.Unmarshal' function is used to 'transfertypes.ModuleCdc.UnmarshalJSON', simplifying the overall structure of the code.

The test for the memo receiver limit now supports four test users instead of two, allowing for more complex transfer scenarios. This change requires increased checks for account balances, as well as additional IBC transfers. This expansion helps ensure more comprehensive testing coverage and overall system validation.
