Add somekind of search for joint chroma residual coding.
Bitstream is currently correct but prediction is incorrect because the jccr
is actually not used in the search.

Copy the kvz_config passed to encoder_open
...
The kvz_config struct is created by the user but kvazaar keeps a pointer
to it. It is easy to break things by modifying the configuration outside
kvazaar. In addition, kvazaar modifies the struct even though it is has
a const modifier.
This commit changes the field cfg in encoder_control_t to be a copy of
the kvz_config struct instead of a pointer, removing modifications to
the const struct and allowing users to do whatever they want with it
after opening the encoder.
