Problems connecting to Gatan camera

[komoto48g]

I am getting an (Infinite loop) error when trying to connect to a Gatan K3 camera using "gatansocket3.py".
After some research, I found this error might be due to a type mismatch: on Windows 10 (64-bit) platform, np.int_ is np.int64 (long long), not np.int32 (long).

For example, the following part raises ValueError: buffer size must be a multiple of element size because the 4 byte chars are being converted into an 8-byte array.

instamatic/src/instamatic/camera/gatansocket3.py

Lines 339 to 345 in f9cf3f7

	# filter name
	filt_str = filt + '\0'
	extra = len(filt_str) % 4
	if extra:
	npad = 4 - extra
	filt_str = filt_str + npad * '\0'
	longarray = np.frombuffer(filt_str.encode(), dtype=np.int_)

Best regards, K

This has been mentioned in #130 and solved by #139.
