propsed fix for spikeglx streamer failing on SDSC because of wrong uuid in file name

[grg2rsr]

previously, the Streamer was instantiated with a absolute path of the meta file (also not ideal in the context of the Streamers constructors call signature, where the first argument is named sglx_file and a dedicated argument meta_file exists. link). While this looks like a bug, it is recovered there in the following lines under normal (=non-SDSC) usage as this line

meta_file = meta_file or _get_companion_file(sglx_file, ".meta")

recoveres the correct file paths.

However, this breaks on the SDSC as the file paths an uuid, and when the corresponding file path for the meta for the bin (or vice versa) are constructed, the uuid is wrong.

The proposed patch checks if the .meta filename contains an uuid, and if so, finds the correct uuid for the .cbin file, constructs absolute paths for both. Either way, uuid or not, the Streamer is now instantiated with both paths for .meta and .bin (or .cbin).

thinking more about this, this could also be patched in a different way, where the uuid completing functionality is added to the _get_companion_file() function in ibl-neuropixel/spikeglx, with a remove_uuid=True as a default kwarg, which is then turned to False either here and passed through the Streamer constructor. This could cover future occurrences of this bug.

SDSC is probably the only place on Earth where we do not need the Streaming functionality ! 😄
