Access to full Penobscot 3D seismic volume (0-6000 milliseconds)

[mycarta]

It would be good to have a full-sized 3D for testing various things, beginning with how the 2D and 3D implementations of FFT scale up.

• Download the full 6000 milliseconds Penobscot project and access 3D volume
• Use OpendTect to export the full milliseconds
• Use segyio to load it and save it a .npy file (example code in this notebook and also the array with samples (values of times in milliseconds for each time slice)
• Store on Dropbox
• Use pooch (here) for retrieval, as suggested by Matt Hall on a discussion on SWUNG, if we want to do everything programmatically
