This commit swaps out Wand (and its non-Python dependencies ImageMagick and Ghostscript) for pypdfium2 for PageImage rendering. This has some advantages: - Less finicky: Wand often caused users problems, due to "MagickWand shared library not found" and "PolicyError: not authorized `PDF'" issues. By contrast, pypdfium2 seems (at least at first) to more self-contained and not require any system-tweaking. - Faster: pypdfium2 appears to render images more quickly than Wand (see @cmdlineuser's tests in #899) - More flexible: pypdfium2 appears to generate images with greater color depth; by default, pdfplumber quantizes those images so that they save/display compactly (in fact, with smaller file sizes than the previous code), this commit also adds parameters to retain all/more of the original, more detailed colors. Thanks to @cmdlineuser in #899 for the suggestion.
