j2k_decompress_reconfigure will check for platform type

j2k_decompress_reconfigure now checks state_decompress_j2k class member platform to see if it is set to j2k_decompress_platform::CPU or j2k_decompress_platform::CUDA prior to calling cmpto_j2k_dec_ctx_cfg_add_cuda_device / cmpto_j2k_dec_ctx_cfg_add_cpu
