support for just .spikes in folder

[ferchaure]

Hi I was trying to load an openephys .spikes file but it required the .continuous file as well. To fix that, I separated a bit better the data loading, all the code was there. And I fixed a typo when the filename is read to check the number of segments.

This will work for my case, but probably a similar fix could be made to load only events files.

Cheers, Fer

Hello @ferchaure! Thanks for updating this PR. We checked the lines you've touched for PEP 8 issues, and found:

• In the file neo/rawio/openephysrawio.py:

Line 495:31: W605 invalid escape sequence '\d'

Maybe the error is related to a unreported renaming in my data, I will check it that and fix it
