Modifications to ATS9870-dev-branch

Changes proposed in this pull request:

• Allow the ATS to work with more than two channels. this was already sort of implemented, but the channels were not provided in binary format, so it did not work.
• Add a _bwlimit_support property to the ATS. Some ATS drivers (such as ATS9440) do not support a bwlimit, and so by setting this property to false, it does not try to set this and recieve an error.
• Move acquisitionkwargs to AcquisitionController. It seems to me that these are funcitonalities that are not only relevant for DFT_AcquisitionController, but to all. I have furthermore added acquisitionkwargs as a parameter, because it will then be saved in a snapshot. For this to work, I had to remove acquisition_controller from the acquisitionkwargs, and hardcode it. I also added some checks to ensure that all kwargs added and retrieved from acquisitionkwargs are actual kwargs used in ATS.acquire()
• Small bug in ATS9870, upon creation of different trigger engines
• Basic_AcquisitionController, which can do simple forms of acquisitions. It has three modes for average_mode. These are:
  • point: Returns a point, which is the average over time and over all traces
  • trace (default): Returns a trace, which is the average over all traces
  • none: Returns all traces, not averaged.

I have not yet been able to fully test the code yet, because I tried to merge the code with the latest version of the ATS9870-dev-branch, and was not able to acquire anymore because the ATS I'm using (ATS9440) retrieves 14 bits, and the latest version of the code only supports 8 bits. I will test it soon, and implement the code for 14 bits as well.

Note that the Basic_AcquisitionController still checks if the buffer recieved does not exceed the total number of buffers. This is still a remnant from the old code, and I believe this has been fixed by Damaz, but I haven't had a chance to test it out yet.
