+This loop copy as many bits that it can each time, crossing
+successively bytes
+Bit missalignement between src and dest
+We can now get src and align it to dest
+Compute the nb of bit we will be able to copy
+Create a mask that will serve in:
+
+
+Then write.
+Compute next time cursors for src
+cross boundary ?
+First bit
+Next byte
+Compute next time cursors for dest
+First bit
+Next byte
+And decrement counter. +
