Path to file not working on Windows about biosppy

[capcarr]

Hi @Arinelle

I'm assuming you are working on Windows, where it is frequent to have problems with path handling within Python. Note that Windows uses the backslash (\) in paths, which is an escape character in Python strings (\b actually represents a backspace ASCII character).

To overcome this, use either raw string literals (does not escape backslashes):
ecg_signal, ecg_mdata = storage.load_txt(r'D:\Data\bitalinoECG.txt')
or escape the backslash:
ecg_signal, ecg_mdata = storage.load_txt('D:\\Data\\bitalinoECG.txt')
