Optionally check for LSL stream name

In addition to checking for a matching LSL stream source ID.

This is useful in the case that a device uses its serial number as its source ID and generates more than one LSL stream: (e.g., a marker stream and a data stream coming from the same device).

This issue comes up with the Neurosity Crown, for example:

>>> import pylsl
>>> streams = pylsl.resolve_streams('eeg')
>>> [(stream.name(), stream.source_id()) for stream in streams]
[('Crown-459 Markers', '4599f267492346b97fda95666a33d868'), ('Crown-459', '4599f267492346b97fda95666a33d868')]

In this case, it is necessary to specify both the host name and source ID to select the correct stream.

Also extends the pylsl Stream connection timeout to the default of 1 second, as recommended by https://github.com/labstreaminglayer/pylsl/blob/master/pylsl/pylsl.py#L535-L538:

Warning: If this is too short (<0.5s) only a subset
(or none) of the outlets that are present on the network may
be returned. (default 1.0)

nice observation, good to know that was the source_id naming behavior for the Crown.

as an fyi, a convention we try to keep for the signature is that verbose is the last argument in the list. we bump it to the end when adding a argument.

I wonder if we should make the change to the _BaseClient instead of the LSLClient. I know that it would likely just be used by LSL clients but it would maintain the underlying object representation for all the different clients.

That sounds good to me!

if I'm understanding this correctly then i would also create a separate error for when the host results in multiple instances and host_name is None

something like
if len(streams) != len(np.unique(streams)) and host_name is None:
ValueError('This LSL stream does not have a unique name, please also specify host_name')
