The merge requests contain 2 main changes:

1. Fix of the pad argument in AudioLoader. It was placed in the wrong class call and there were not tests to check audio frames when pad=False. I corrected this bug. This was a very simple fix and I added another test to check for this condition.

2. I created 4 new utility functions: ceil(), floor(), ceil_round_down() and floor_round_up(). They are documented, please tell me if the description makes sense.

Ceil and floor are essentially the equivalent of numpy functions but they allow to round up to a decimal case instead of to an integer. The functionality is exactly the same as np.round() with the decimal parameter (I dont know why numpy doesnt implement the same thing).

ceil_round_down and floor_round_up help deal with floating point arithmetics (see documentation of the functions for further description). For example np.floor(21.9999999998) will result in 21. With floor_round_up(21.9999999998, decimals=6) for example, it will round up to 22.

If you can come up with a better name for these two functions that would be great.
