If you know the index of your desired range, you can now use that
index directly and skip the usual call to `find_range`.

Don't set log levels for pycomedi.LOG handlers.
That's too much granularity for the default situation, where there is
only one handler and we can use the logger's level to control
verbosity.

Fix error condition `ret < 0` -> `ret < len(insnlist)` for Device.do_insnlist.
The previous implemenation would apparently succeed if there was an
error executing an instruction. It would only raise an exception if a
failure occured before the first instruction could be executed.

Revert "Mask range.unit with 0xff when determining the unit."
This reverts commit
d721a0c05450c793a5e0e562d286a689565cf81b.
From the National Instruments E Series User Manual [1], page 3-2:
Reference Selection
(NI 6020E, NI PXI-6040E, NI 6052E, NI 6062E, NI 6070E/6071E, and
PCI-MIO-16E-4 Devices Only) You can connect each DAC to the device
internal reference of 10 V or to the external reference signal
connected to the external reference (AO EXT REF) pin on the I/O
connector. This signal applied to EXT REF should be within
±11 V. You do not need to configure both channels for the same mode.
So RF_EXTERNAL is a valid unit (i.e. in units of the AO EXT REF
signal). The next commit will add this unit.

Add __reduce__() method to BitwiseOperator and _NamedInt.
This makes it possible to successfully pickle and deepcopy instances
of these types [1,2]. This gets the
TRIG_SRC.now == copy.deepcopy(TRIG_SRC.now)
doctest working, which I needed to successfully dump h5config
ChoiceConfig objects that use _Enum choices [3].
For example, the newly fixed pypiezo.config.ChannelConfig [4] uses the
AREF enum values as possible choices for it's `analog-reference`
setting. h5config makes deepcopies of mutable objects to avoid
confusion if the mutable is changed externally. It then compares the
deepcopies with uncopied values. Now that deepcopying works for
_NamedInts, the h5config behavior will work.
