Support lettuce 6.5

What Does This Do

Add support for lettuce 6.5 and extend testing.

Avoid using name while using toString (generally works ok on previous versions since commandKeyword are enums and toString is not overridden)

Thanks for the fix. I also did a bit of research and found a small caveat. This won't work for versions from 5.0.0.Beta to 5.1.0.M1 because StringCommandType.toString was only added in the latter version.

Which is just a few very old releases:

5.0.0.Beta1
5.0.0.M2
5.0.0.RC1
5.0.0.RC2
5.0.0.RELEASE
5.0.1.RELEASE
5.0.2.RELEASE
5.0.3.RELEASE
5.0.4.RELEASE
5.0.5.RELEASE

And even if someone still uses it, the only problem will be that instead of a string command name it will use the auto-generated StringCommandType.toString, which doesn't seem to be a big problem at all.

@ygree thanks. I imagined that the toString generally delegates to name. I think that's acceptable to live with this caveats
