Create an OSC message from a string

[sphaero]

Problem: it's not easy to create a message simply by describing it like how a message can be printed as a string
Solution: Add zosc_fromstring method enabling the creation of message from a string

Also added test code.

A message can be constructed as follows:

zosc_t* msg = zosc_fromstring("/stringmsg ihfdscF 32 64 1.100000 3.140000 hello q");

No idea why.

Valgrind check is failing on zhttp_client?
