Awg5014 with channels

+The ``TektronixAWG5014`` driver has been refactored to use ``InstrumentChannel``
+submodules. Per-channel parameters (e.g. ``amp``, ``offset``, ``state``) are now
+accessed via ``awg.ch1.amp`` instead of ``awg.ch1_amp``, and marker parameters
+via ``awg.ch1.m1.high`` instead of ``awg.ch1_m1_high``. The old flat attribute
+names still work but emit a deprecation warning. The example notebook has been
+updated accordingly.
