if a single text file name is supplied as argument
(e.g.: 'webpmux my_long_list_of_frames.txt'), the command
line arguments are actually parsed from this file.
Tokenizer will remove space, tabs, LF, CR, returns, etc.
+ changed ImgIoUtilReadFile() to return a null-terminated
data, for convenience.
+ misc clean-up in the code

WEBP_MAX_IMAGE_SIZE can be defined to control this limit.
Set it to 1.5GiB w/--config=asan-fuzzer to avoid OOM with large resolution
images. This limit leaves some headroom over the single image max of 2^14 *
2^14 * 4
