v2_compat does not provide shims for ToggleableOutputPin

[little-arhat]

error[E0599]: no method named `toggle` found for type `alt_stm32f30x_hal::gpio::PA1<alt_stm32f30x_hal::gpio::PullDown, alt_stm32f30x_hal::gpio::Output<alt_stm32f30x_hal::gpio::PushPull, alt_stm32f30x_hal::gpio::HighSpeed>>` in the current scope

   = note: the method `toggle` exists but the following trait bounds were not satisfied:
           `alt_stm32f30x_hal::gpio::PA1<alt_stm32f30x_hal::gpio::PullDown, alt_stm32f30x_hal::gpio::Output<alt_stm32f30x_hal::gpio::PushPull, alt_stm32f30x_hal::gpio::HighSpeed>> : embedded_hal::digital::v2::ToggleableOutputPin`
   = help: items from traits can only be used if the trait is in scope
help: the following trait is implemented but not in scope, perhaps add a `use` for it:
   |
6  | use embedded_hal::digital::v1::ToggleableOutputPin;

Can be solved in hal implementation by providing v2::toggleable implementation:

impl<PT: PullType, OT:OutputType, OS:OutputSpeed> v2::toggleable::Default
    for $PXi<PT, Output<OT, OS>> {}

But would be nice to have it provided by this crate.
