Update vcd_ddl_core.h

Increased bitrate/raised for h263 ( MPEG4 Visual encoder ) up to 100mbps ( easy logic ).,

SMALL PATCH.
#define DDL_MAX_BIT_RATE    (20*1024*1024)
to
#define DDL_MAX_BIT_RATE    (100000000) or (100*1024*1024)

Only part of the code is used, the rest seems to dont work or disabled.

( im still unable to unlock h264 ).
