[FFmpeg-devel] doc/muxers: correct decribe of hls_enc_key and hls_enc_iv

From: Steven Liu <liuqi05@kuaishou.com>

because hls_enc_key and hls_enc_iv get 16byte char
for example:
-hls_enc_key 0123456789abcdef -hls_enc_iv abcdefghijklmnop

8216 said " [AES_128] encryption uses 16-octet keys.  If the KEYFORMAT of an EXT-
   X-KEY tag is "identity", the Key file is a single packed array of 16
   octets in binary format."
