added tcp to the list of accepted schemes

[esokullu]

Currently tcp scheme is not accepted. It is accepted with predis and others. For compatibility with other libraries, I suggest you include it as well.

Thank you for your contribution!

The redis:// URI scheme has been added not too long ago via #60 and the (previously supported) tcp:// scheme has been removed via https://github.com/clue/php-redis-react/pull/61/files#diff-8157a0d28a58887c0293ce14b4b0281fL112.

I'm not sure I follow what the motivation for bringing this back is, so maybe you can elaborate? It's my understanding that the redis[s]:// URI schemes are standardized via https://www.iana.org/assignments/uri-schemes/prov/redis and https://www.iana.org/assignments/uri-schemes/prov/rediss respectively and I would rather see these supported in all Redis client library, no?

@esokullu uniformity (rather than compatibility) is exactly the reason why the redis:// scheme was introduced and standardized, which also makes this the main reason why libraries should support this scheme and its rules before anything else. Historically other libraries using tcp as a scheme always parsed and interpreted parameters in the URI in their own way because there were no defined and fixed rules, so simply allowing tcp:// doesn't actually mean anything in this context.

I'm closing this for now as it hasn't received any input in a while and I believe this has been answered. Please come back with more details if this problem persists and we can reopen this 👍

Either way, thank you for looking into this @esokullu!
