Release v0.10.0

Breaking changes

• Update stm32f3 pac to v0.15.1 (#335)
• Update bxcan pac to v0.7.0 (#335)
• Remove Toggle enum and use Switch instead for better naming purposes
• Fix undefined behavior in SPI implementation (#346)
  • Add num_traits::PrimInt bounds to Word
• Remove Serial::split, which possibly creates two mutable references two
  one Serial instance, which could've caused UB. The use case of this function
  was hard to find out anyway. (#351)
• Remove defmt-* features (defmt feature is still available), to finalize
  migration from defmt-0.2.x -> defmt-0.3.x. (#349)
• Removed implicit stm32-usbd feature (use usb instead) (#349)

Added

• Add missing ADC channels (#337 & #345)
• Add many #[must_use] instances (#347)

Fixed

• Fix wrong timer frequency calculation and unexpected panics (#338)
• Fixed integer saturation in Timer::start, see #342 (#356)

Changed

• The PWM implementation was deprecated. There is not yet an alternative
  implementation, but it is hard to maintain the current implementation
  and not easy to verify if it is really a safe implementation.
  It is also not consistent with the rest of the crates API. (#352)
• Use critical-section crate instead of interrupt_free, which is not always
  sound. (#350)
  It is also not consistent with the rest of the crates API.
• The MSRV was bumped to 1.60 (#349)
