Changed namespace

[jrbasso]

Moving the namespace from Zumba\Util to a namespace just for the project (Zumba\JsonSerializer). I am planning to add more classes, interfaces and traits, which will add things that are not necessarily part of the Util namespace.

Also, other open source projects that we have also have dedicated namespaces.

PS: The JsonSerializer class is the same, just changing the namespace at the top and the exception namespace. It is just how GitHub shows the file change. On the repo it was a file rename.

@jrbasso If you specify JsonSerializer here, you can move the actual class to the root of the src/ directory (per PSR4).

@cjsaylor As we talked in person, this was left intentionally to keep the BC with the existent namespace. I marked as deprecated on this version.

@jrbasso Also, needs a rebase.

What do you think in removing the BC compatibility and just adding a note about it in either the readme or adding a changelog file? If we bump the major version it should be known that there are BC breaking changes.
