Added a violation fix for adc conversion of channel buffers (#166)

* Refactor _adc_to_ method in PicoScopeBase (base.py) to improve buffer handling

* Renamed parameter 'data' to 'buffer' for clarity.
* Enhanced buffer processing to handle both channel_buffer dictionaries and single values.
* Updated conversion logic to ensure consistent output for different input types.

* Upversioned to 1.6.5
