SigProcLib: Use available copyTo Vector API instead of memcopy 

This change allows to remove some wrong use of code as per compilation
warning:
osmo-trx/Transceiver52M/sigProcLib.cpp:1266:40: error:
‘void* memcpy(void*, const void*, size_t)’ writing to an object of non-trivially copyable type ‘class Complex<float>’; use copy-assignment or copy-initialization instead [-Werror=class-memaccess]
   midMidamble->size() * sizeof(complex));
