Release v0.4.0

[robin-nitrokey]

Added

• Added Path::from_str_with_nul and path! to create Path instances from
  str.
• Added Eq and PartialEq implementations for Path.

Changed

• Made Path::from_bytes_with_nul_unchecked const.
• Replaced LOOKAHEADWORDS_SIZE (measured in multiples of four bytes) with
  LOOKAHEAD_SIZE (measured in multiples of eight bytes) in driver::Storage
  so that all possible values are valid. (See the lookahead size fix below for
  context.)
• Require &mut self in driver::Storage::read for compatibility with
  embedded_storage.

Fixed

• Fixed the lookahead size reported to littlefs2-sys. Previously, the
  reported size was too large by the factor of 8, potentially leading to a
  buffer overflow causing filesystem corruption. Fixing this means that
  Storage::LOOKAHEADWORD_SIZE values that are not a multiple of 2 can now
  lead to an error. Fixes #16.
• Propagate errors in littlefs callbacks instead of panicking.

I'd add that we expect bumping 0.3->0.4 to not break existing data (and optionally be more clear about which are the two semver-breaking changes requiring the bump).

If there is an unexpected data break, we'd try and fix with a 0.4.1 and yank 0.4.0, correct?

Yes, that would make sense to me.

Maybe add "The Trussed developers"
