INT_MAX/2 might be better to avoid possible overflows with padding or
pes header. Or simply 1 GiB, after all, a corrupt PID might consume
RAM up to this amount, so preferably it should not be too big... Docs
needs update accordingly.
Also since MAX_PES_PAYLOAD define is no longer used in the code, I'd
just remove it and put its value directly here as the default.
Will change to INT_MAX/2 and push.
Thanks,
Gyan
