4bd5d6b609 kimgio: cast the character to uchar and return EOF on error from RAWDataStream::get_char() 
note that LibRaw_buffer_datastream returns -1 if the position is
out-of-bounds but https://www.gnu.org/software/libc/manual/html_node/EOF-and-Errors.html
claims that EOF may not be -1

9526e164cb kimgio: hardcode RAW image MIME types 
the plugin is heavy on I/O already because LibRaw requires the whole file
data to determine if it can open it or not so this will reduce that a bit
at the cost of (possibly) requiring update in the future
