ToruNiina cbaaaaca7c revert recursive find function
I found that in a user-code (I'm also one of the users of this library),
this new feature sometimes causes an error. Some of my code won't
compile because of this change. Since toml::table is convertible to
toml::value *implicitly*, if toml::find(table, key, tablename) was
called, the overload resolution becomes ambiguous with toml::find(
value, key1, key2). But dropping support for toml::find(toml::table,
key, tablename) is a breaking change. So I concluded that now is not
the right time yet.
