Press the 'start' button in the Saleae Logic 2 gui

saleae.py

# The Saleae Logic 2 GUI has a scripting API, but it's designed for full automation, and doesn't
# seem to have a method for telling the GUI to just start a capture. So forget it, let's just
# invoke the button ourselves...
#
# Tested with Windows 10 and Saleae Logic 2.4.3, you'll likely need to tweak this
