Do a release

[jonathanpallant]

Once #95 is in, we should do a breaking change release.

cargo semver-checks says:

• field AcquireOpts.acquire_retries in C:\Users\msn\Documents\GitHub\embedded-sdmmc-rs\src\sdcard\mod.rs:633
  • Adding a pub field to a literal constructable struct is a breaking change
• struct embedded_sdmmc::Controller, previously in file C:\Users\msn\.cargo\registry\src\index.crates.io-6f17d22bba15001f\embedded-sdmmc-0.5.0\src\volume_mgr.rs:16
  • I removed the Controller alias

So it will be 0.6.0

Now we need to do 0.7 with the smart handles.

and the new mkdir support in #111.

But probably before we merge #106.

I noticed these have been merged, maybe close this issue? @thejpster 😅
