cb8f879b92 Add parse_env attribute to confique::Config macro 
Since there is no established format for representing collections within env variables, to enable their support, the feature with a custom parser attribute added.

Add helpers for parsing env variables into collections

Improve rustdoc for `env_utils` functions

Improve `parse_env` example

2bf2727875 Mark some types in meta as #[non_exhaustive]

52b9369f9a Make all FormatOptions #[non_exhaustive] 
This is to make adding fields to those structs a non-breaking change.
This unfortunately means that users cannot use the struct initializer
syntax anymore. They have to create a mutable variable and change fields
that way. It's slightly annoying, but I think we want `non_exhaustive`.

Also, there are multiple discussions and pre-RFCs for letting Rust allow
the struct initializer syntax when the type implements `Default`. So
maybe this will improve in the future.

4533f2b2d4 Fix visibility of template module and items 
The trait and `template::format` are now crate-private as I don't want
to expose that API surface (alongside the `TomlFormatter` types).

6a9ccd4e22 Do major refactor of format code 
This gets rid of a lot of duplicated logic that was previously
copy&pasted. This commit alos:
- Makes it easier to implement new formats
- Gets rid of a few bugs
- Makes the system more flexible (more options)
- Adds a lot of additional tests

44f59f415a Implement Serialize for meta::Expr and use it in PrintExpr 
This probably fixes a few edge case bugs (float infinity and stuff) and
results in less code.

eb03488973 Fix using env with deserialize_with 
Fixes #2

I simply forgot to use the `deserialize_with` attribute for the env
deserialization. The previous code was somewhat weirdly coded in that
we would always deserialize `Option<T>` (as it's a partial type) and
the "env variable not present" info would travel through the
deserializer to the `Option<T> as Deserialize` impl. Now it's more
straight forward.

e801403009 Fix output of toml::format by always handling leaf fields first 
Otherwise this:

```
struct Config {
    #[config(nested)]
    foo: ...,
    bar: ...,
}
```

would emit:

```
[foo]

```

Which is incorrect.

ebd8aba2fa Disallow Option<_> type for fields with #[nested] or #[default] 
Regarding nested fields: I cannot imagine a situation where that
distinction is useful. Also, specifying an empty nested object looks
stupid in TOML and YAML anyway.

Regarding default fields: If there is a default value, then the field
should not be declared as optional to begin with.
