'&' in key-file URL gets parsed out

[Pfuenzle]

In the method parse_tag in hls.c, in line 284 & 285 (

hlsdl/src/hls.c

Line 284 in 84c1ded

if ((sscanf(tag, "#EXT-X-KEY:METHOD=AES-128,URI=\"%[^\"]\",IV=0%c%32[0-9a-f]", link_to_key, &sep, iv_str) > 0 ||

)
, where the URL to the key-file gets parsed, if the link is containing a '&', the & and everything after it gets ignored. This causes a 404 error, if that part is needed for a working URL, as seen here: #81

I tried some thing to make it not ignore it, but I was not able to, as Im not familiar with this kind of parsing
