[AT3P] Use a bit speed optimised libgha.

sin/cos computation with double precision inside libgha cause
significant cpu usage. Actualy we do not need such presition
due to discrete values in the bitstream.

New libgha version also does not perform multiple float to double
conversion in the hot loop (although it can be not good from cache
locality perspective). But it still gives speed up on modern CPUs.
