Update ecephys align timestamps to allow barcode_ephys line label variant

[wbwakeman]

The get_barcode_line of the align_timestamps module searches for barcode in several variations of sync file line labels that have been encountered. There is a new variation used by Visual Behavior Neuropixels: ephys_barcode

As defined in the excel file linked in the "Sync: PCIe 6612 DAQ" section of this confluence page.

Need to enable processing using this new line label. (Add another elif?)

Probably worth checking if there are other places in the code where the new line labels break old implementations.

More details:

Simple fix would be to add new elif clause to:

We may want to consider this an opportunity to move the whole align_timestamps module over to the ecephys_etl_pipelines repo though:

https://github.com/AllenInstitute/AllenSDK/tree/master/allensdk/brain_observatory/ecephys/align_timestamps

Validation:

• [x] (if moving code to ecephys_etl_pipelines) Confirm that old Visual Coding Neuropixel sessions still run through this module without issue
• [x] Able to run Visual Behavior Neuropixel sessions through the align_timestamps module

Estimate of 1-2 if just putting in the fast fix. Estimate of 3-5 if moving the whole module over from AllenSDK + putting in fast fix
