    README: apply the review of PR #1858

    Follow-up to the two preceding commits, which were not updated after the review.

    heif-enc does write MP4 video, with the --video option, so restore that half of
    the sentence rather than dropping it.

    Keep "libheif comes with" lowercase. The README opens sentences with a lowercase
    "libheif" in nine places and with "Libheif" in two, so capitalizing here moved
    towards the minority spelling.

    Add the missing "or" in the two heif-dec output lists, in the Usage and the
    Example programs sections.

    Also mention raw pixel data. heif-enc reads it from files with a .raw or .img
    suffix (and with --raw for other names), which neither the old nor the new text
    said.

    The codec table itself is correct: decoder_ffmpeg.cc answers
    ffmpeg_does_support_format() for HEVC, AVC, VVC, AV1, JPEG, JPEG 2000 and HTJ2K,
    and there is no ffmpeg encoder plugin. heif-dec writes jpg/jpeg, png, tif/tiff,
    webp and y4m; heif-enc reads those plus raw/img and heif/heic/hif/avif/avifs.
