folder discovery for dependency scipt

[faradaym]

This is a fix for the dependency automation script so that it can dynamically find the libraries folder from the script folder. This PR also adds a requirements.txt for the script according to python standard. Thanks to @amirna2 for this solution!

Is this a patch, a minor version change, or a major version change
Patch.

Some of the libraries were already installed in my macOS and it threw an error saying that the directory already exists. Any thoughts on what we should do? Do we ignore the installed packages or do we overwrite them to make sure the version is consistent with CDP?

Traceback (most recent call last):
File "/Users/tqrahman/Documents/Arduino/libraries/ClusterDuck-Protocol/cdp-dependency-automator-script/install-dependencies.py", line 29, in
with open(file_path, 'wb') as file:
IsADirectoryError: [Errno 21] Is a directory: '/Users/tqrahman/Documents/Arduino/libraries/arduino-timer'

However, when I removed the libraries and ran the script again and it worked like a charm!
