Why is the event channels header dtype is in bytes?

[h-mayorquin]

So here:

_event_channel_dtype = [
    ("name", "U64"),
    ("id", "U64"),
    ("type", "S5"),  <---- HERE ATTENTION THIS IS BYTES
]

I think this might bring problems down the line. Is this intentional? it seems to me that it should be strings and in fact in Plexon is extracted as a string and implicitly converted to bytes when the header is built.
