feat(read_cwa): add command-line options for time range trimming

Adds new command-line options to the read_cwa.py script for specifying a time range and customizing data extraction:

--start-time: Specify the start time for data extraction.
--end-time: Specify the end time for data extraction.
--skipdays: Number of days to skip before starting extraction.
--cutdays: Number of days to exclude from the end of the range.

These use existing functionality in read_device that were added recently but were missing in the CLI.
