self-replace

• Raised MSRV to 1.63 and upgraded windows-sys to 0.52. #26

• Added self_delete_at. #22

• Fix windows dependency. #16

• Change the dummy command to use on windows away from ping.exe to cmd.exe.

yanked invalid release

• Avoid the use of atexit and spawn immediately. This has the advantage that even if the process crashes hard, we already have started the cleanup handler.
• Improve safety of the crate for Windows by avoiding unsupported life before main.

• Use an atomic rename on Windows in the self replacement case for the final step to avoid accidentally leaving partial executables behind.
• Resolved an issue where a potentially incorrect filename was computed on Windows in some cases.
• A temporary folder is now always preferred on windows for the temporary operations if possible. This code path now also works correctly.

• Fixes a bug that caused the wrong path to be calculated internally creating an access error in some cases.

• Added support for self_delete_outside_path to support more complex uninstallation scenarios on Windows.

• Improve a race condition on Windows.

• Support older rustc releases.

• Initial release.
