Inconsistent save_samples and load_samples definition in peregrine.samples

[sudiptakarmakar]

The declaration for save_samples is
def save_samples(filename, samples, file_format='int8')

and declaration for load_samples is
def load_samples(filename, num_samples=-1, num_skip=0, file_format='piksi')

Because of that, passing minimum number or arguments, if you save a sample it saves in np.int8 format, but when loading, it tries to retrieve that saved sample in piksi format. As a result, returned object is often starkly different from what was saved at first.

Thanks, indeed we should make that consistent. I'm planning to merge a lot of updates into the master branch of peregrine soon, and will address this.
