Can add information?

Can you add information here (https://github.com/credo-science/credo-api-tools/tree/master/data-exporter) on how to download detections from a given time? for example:

You can download everything by default, or decide yourself from what date.
For this purpose, in the main directory (ie "credo-data-export") in the "last_exported_detection" file (if there is no file to create it) enter the date in the appropriate format - timestamp.

The date in this format can be obtained, among others, on the website:
https://www.unixtimestamp.com/index.php
By entering the year, month, day and then clicking on "convert" - this way we get a 10-digit date with an accuracy of the second. The file should contain the date with the accuracy of a microsecond, (add 3 zeros to the end).
Example:
The website includes the date: May 25, 2020
we get: 1590364800
we add 3x0 to finally have: 1590364800000

And in this way, we will only download data from May 25, 2020.

Start by reviewing the documentation in the data-exporter directory and how the last_exported_detection file is used. Add instructions covering the default full download, creating or editing the file with a microsecond timestamp, and checking the resulting date-based export behavior; the documentation should be understandable without external context.
