This pull request introduces several changes.

The first patch (1/3) adds a new file options.go to the pkg/relayer/session package, which contains a new function WithStoresDirectory. This function sets the path on disk where KVStore data files are created.

The second patch (2/3) adds a small improvement to the WithStoresDirectory function. It changes the error message when the session tree store path already exists.

The third patch (3/3) improves the readability of the error messages in the errors.go file. It updates the error codespace and the error messages to make them more descriptive. It also updates the error message when the session tree store path already exists.

Overall, these changes aim to enhance the management of sessions and their corresponding data files in the relayer package.
