DYNA/ITACA read/write support

Just stumbled over this mail: http://lists.swapbytes.de/archives/obspy-users/2014-January/001164.html
Just adding these files pretty much as is to make everybody aware of this development, I hope the original authors can comment on the status.
This is pretty inefficient. `np.append` should be avoided in almost all cases, and the inner `for`-loop does in 5 lines what could be done in 2! It should be possible to just do:
```
data_1 = data[:,0]
data_2 = data[:,1]
```
