Update to ImageMagick 7.1

[ViralBShah]

ImageMagick 7.1 is now in Yggdrasil. JuliaRegistries/General#105903. Would be nice to get this package to upgrade. I imagine the upgrade may not be easy or straightforward, and hence opening this issue to see if someone might be interested in trying it out and seeing what it takes.

Dup of #69. cc @musm.

Keeping this one open instead of the older one, so that it is on top.

Just casually bumping the version number in Project.toml yields various issues. It seems that the ImageMagick 7 does not have the GetImageChannelDepth API any more:

        Info Packages marked with ⌃ and ⌅ have new versions available. Those with ⌃ may be upgradable, but those with ⌅ are restricted by compatibility constraints from upgrading.

[dgleich]

Okay, I've been looking at this update... the stuff with image channel depth is easy to fix as you can just remove the getimagechanneldepth'' calls and replace them with getimagedepth'', which I think now does the same thing.

But after that issue, I'm running into a weird issue where ImageMagick seems to flip the interpretation of binary images entirely between 6 and 7. So all the tests on binary images break. (And then there are a few more after that...)

[ViralBShah]

Fixed in 0bd5d85 by @dgleich. Should also close #206

Need to update the README (which mentions ver 6)
