Improved robustness of the PDF structured content extraction mechanism.

Added support for the following file types:

• Image (GetMetadata): 3fr, arw, avci, avif, bmp, cr2, cr3, crw, dng, eps, epsf, epsi, gpr, heic, heif, icb, ico, kdc, nef, orf, pbm, pcx, pef, ppm, psd, raf, rw2, srw, tga, tif, vda, vst, webp.
• Audio (GetMetadata): m4a, m4b, m4p, m4r, wav, wave.
• Video (GetMetadata): avi, crm, m4v, mov, mp4.
• Archive (GetText): tar.

Removed the ability to pass a file URL as an alternative to binary input. This feature was added to ensure compatibility with the ODC version, but I came to the conclusion that it does not add value and makes the component interface less clear.
