Outdated doc-comment for trait Format (?)

[Urhengulas]

It seems that the doc-comment for the trait Format is outdated. Definitely the "Note that [write!] can only be called once, as it consumes the [Formatter].". Maybe also the section about the manual implementation?

defmt/src/traits.rs

Lines 7 to 46 in 149c0ef

	/// Trait for types that can be formatted via defmt.
	///
	/// This trait is used by the `{:?}` format specifier and can format a wide range of types.
	/// User-defined types can `#[derive(Format)]` to get an auto-generated implementation of this
	/// trait.
	///
	/// **Note**: The implementation of `#[derive(Format)]` assumes that no builtin types are shadowed
	/// (for example by defining a `struct u8;`). This allows it to represent them more compactly.
	///
	/// # Example
	///
	/// Usually, an implementation of this trait can be `#[derive]`d automatically:
	///
	/// ```
	/// use defmt::Format;
	///
	/// #[derive(Format)]
	/// struct Header {
	/// source: u8,
	/// destination: u8,
	/// sequence: u16,
	/// }
	/// ```
	///
	/// Manual implementations can make use of the [`write!`] macro:
	///
	/// ```
	/// use defmt::{Format, Formatter, write};
	///
	/// struct Id(u32);
	///
	/// impl Format for Id {
	/// fn format(&self, fmt: Formatter) {
	/// // Format as hexadecimal.
	/// write!(fmt, "Id({:x})", self.0);
	/// }
	/// }
	/// ```
	///
	/// Note that [`write!`] can only be called once, as it consumes the [`Formatter`].

@Dirbaio Can you please update this? 😁
