Add option to view only a specific shank to BinaryFile

[JoeZiminski]

This is a bit of a prototype PR but would be good to get your thoughts @oliche. For some data I have it sorted per-shank so it is nice to look only at that shank up-close. This PR adds an option to display only a selected shank.

I'm not sure if this is the best way to split the shank through the IBL API, I also only tested it for spikeglx.Reader so not sure if it will work for ReaderClass.

In general this should be better tested, and will have to be updated a lot once loading from spikeinterface is also supported. In terms of testing, I wonder if its easier to maintain a list of things to test, as there may be a lot of upcoming changes (e.g. spikeinterface reader, loading sorting output). Once we are happy with the form we can add a load of tests?

Add an edit box, we'll use the syntax to filter using header.
For example:

shank 0 selects only shank == 0
shank 1 3 selects shank one two and three
shank 1 3 2 selects from shank one to three with a 2 increment: so shanks 1 and 3
