Added

- Replicate the optimization used by Excel where it only stores one copy of a
repeated/duplicate image in a workbook.

Added

Added

- Added support for inserting images into worksheets with
[`Worksheet::insert_image()`] and [`Worksheet::insert_image_with_offset()`] and
the [`Image`] struct.

features such as EMF and WMF formats, removal of duplicate images, hyperlinks
in images and images in headers/footers.

Added

- Added support for writing hyperlinks in worksheets via the following methods:

- [`Worksheet::write_url()`] to write a link with a default hyperlink format style.
- [`Worksheet::write_url_with_text()`] to add alternative text to the link.
- [`Worksheet::write_url_with_format()`] to add an alternative format to the link.

- Reduced the `zip` dependency to the minimum import only.
- Removed dependency on `tempfile`. The library now uses in memory files.
