Unable to access nested tables

[Lucki]

This example is directly from the toml.io page:

[dog."tater.man"]
type.name = "pug"

But trying to access them with doc["dog"]["tater.man"]["type"]["name"].as<string> () fails with:

[ERROR] Nothing at `dog`.

Here's a simple example for your tests which outputs the error in the log.

Bonus issue:
You're not using your environment variable G_TEST_SRCDIR inside your tests so the tests /toml-glib/parser/file and /toml-glib/parser/whole-spec fail with

[ERROR] Failed to open file ?test.toml?: No such file or directory
not ok 12 /toml-glib/parser/file
[ERROR] Failed to open file ?all.toml?: No such file or directory
not ok 13 /toml-glib/parser/whole-spec

Bonus issue:
With the above file issue fixed I expect all.toml to fail or throw errors because it contains invalid configurations but it doesn't.

I'm no longer maintaining this library to be honest, but if you want to submit a patch I will accept it.
