Issue with wand import not being found about pydngconverter

[BradenM]

Hi @kevflynn, thanks for the detailed report.

First, I do want to mention that Wand is only required (and is conditionally imported for) using the flags.JPEGPreview.EXTRACT flag. This flag is an alternative to the dng converter built in jpeg extraction (available to use via JPEGPreview.MEDIUM/FULL) or can be disabled all together via JPEGPreview.NONE.

If you do require/want the EXTRACT method, I would recommend digging through the Wand docs:
https://docs.wand-py.org/en/latest/guide/install.html#install-imagemagick-on-mac

This issue is more of a Wand problem rather than a pydngconverter issue, but if you are still running into problems here, I am glad to try to help out. Thanks.
