     * Contrary to other implementations this IO reads the entire folder and subfolders and:
       deals with several segments based on the `_gt0`, `_gt1`, `_gt2`, etc postfixes
-      deals with all signals "imec0", "imec1" for neuropixel probes and also
-      external signal like"nidq". This is the "device"
-    * For imec device both "ap" and "lf" are extracted so one device have several "streams"
-    * There are several versions depending the neuropixel probe generation (`1.x`/`2.x`/`3.x`)
-    * Here, we assume that the `meta` file has the same structure across all generations.
