Extract specific time blocks from a set of miniseed files.

Reads a large set of miniseed files, trims out specified time block(s), and writes the trimmed block(s) to disk.

• data_dir (str, optional) – The full or a relative file path to the directory containing the miniseed files, default is the current directory.

• output_dir (str, optional) – The full or a relative file path to the location to place the output miniseed files, default is the current directory.
