This handles NaN and both positive and negative infinity.

This ensures consistency with the default `Formatter::write_f32` output
format used elsewhere.

`deserialize_numeric_key!` has been renamed back to
`deserialize_integer_key!`, and a new float-specific
`deserialize_float_key!` macro has been introduced.

This new macro attempts to deserialize float keys by delegating to the
equivalent parent deserializer method.

An `unwrap` has been changed to simply discard the `Result`. We assume
that writing to a `Vec` will never fail because the `std::io::Write`
implementation never creates an I/O error.

Allow `f32` and `f64` map keys

Improve error message on invalid numeric key
