We were using whatever precision the underlying file system was giving us, and in some cases that can be very detailed. Some formatters mess with the mod time, but not to the same precision (e.g. dos2unix).
POSIX also specifies that mod time should be EPOCH (second) precision.
This change brings us back in line with how 1.x worked, and should resolve issues with false fail on change errors.
This was incorrectly ported from Rust to Go.
When `--stdin` is provided, `treefmt` copy the `stdin` into a temporary file, using the first path argument as the filename. This allows the user to control which formatters will match this temp file based on their `treefmt` config.
After the formatters have been applied, the contents of this temporary file are then printed to stdout and the temp file is removed.

This was incorrectly ported from Rust to Go.
When provided, `treefmt` will take the contents of stdin and place them into the file provided with the `--stdin` flag, then format it according to the configured formatters.
If the file doesn't exist it is created. If it exists, it is first truncated and then populated with stdin.
