Nathan Harris 06471a2a39 Change RedisClientError from enum to struct
Motivation:

The current state of Swift does not leave room for library evolution of enum types used for `Error`.

To avoid having to increment Major SemVer to add a new error case that might be needed to fix a bug, the `enum-like struct` idiom should be used.

Ideally this idiom will disappear, when Swift provides a way for Swift Packages to have a "library evolution" capability.

See https://forums.swift.org/t/extensible-enumerations-for-non-resilient-libraries/35900

Modifications:

- Change: `RedisClientError` to be struct with private enum value

Result:

Should new error cases be necessary to add, they can be in Minor SemVer releases, rather than Major SemVer.
