EventReader,PlistEventWriter: Change use `base64::STANDARD` for `Data`data-without-base64-mime

Use `base64::STANDARD` instead of `base64::MIME` to encode `Plist::Data`
types.

Using `base64::MIME` formats the base64 string with:

    LineWrap::Wrap(76, LineEnding::CRLF)

(https://docs.rs/base64/0.9.3/base64/constant.MIME.html)

In an XML plist using `\n` line endings, the base64 string gets broken
into `\r\n`, mixing line endings.

The `STANDARD` configuration doesn't wrap lines at all, bypassing the
whole problem.
