After updating to v.0.3.0, the following TOML is now rejected by the decoder:

[one.two]
hello = "world"

[one.two.three]
foo = "bar"

with an error:

• Value |4, 15| Using dotted keys to add to [one.two] after explicitly defining it above is not allowed"

I see references to invalid combinations of implicitly/explicitly defined tables in TOML spec v.1.0.0, and compliance tests (1, 2) around that structure, however I don't see anything in the spec that restricts extending a table like the example above shows. In fact, toml++ v.3.4.0, via TOMLKit, indeed accepts this structure.

As such, this seems like a regression to me, introduced in #53. Am I missing something? Thanks!
