0.7.0 - 2025-09-30

Make Write::flush() a required method, aligning with std and embedded-io
Update to and align with embedded-io 0.7:
- Error type is updated to include core::Error
- Update defmt dependency to 1.0; rename feature from defmt_03 to defmt
- Require Read and Write to be implemented for various Read and Write traits
- Fix missing method forwardings for blanket implementations
- Documentation updates
Implement Read, ReadReady, BufRead, Write, and WriteReady for VecDeque<u8>

Use feature() on nightly toolchains only. This adds support for 1.75 beta and stable.

Prohibit Write::write implementations returning Ok(0) unless there is no data to write; consequently remove WriteAllError. Update the &mut [u8] impl to possibly return a new SliceWriteError if the slice is full instead of Ok(0).
Add WriteZero variant to ErrorKind for implementations that previously may have returned Ok(0) to indicate no further data could be written.
Write::write_all now panics if the write() implementation returns Ok(0).
