Wiki contribution: Add a guide on how to use the scripts

[2320sharon]

The scripts in coastseg aren't included in the pip package. Make sure to add them and create a guide on how to use them so that users can use them

• Add the scripts to the official pypi package
• Fix the scripts so that they work on the new transects in issue US slope database #134
• Fix the scripts so that they work on regular transects files
• Add a guide on how to run the scripts
• Add a guide on how to open each script in python in notepad ++

It turns how including executable scripts in the pip package is not as simple as just adding the scripts directory to the MANIFEST.in. My initial research leads me to believe this will take a bit more work to configure correctly. I may to modify the pyproject.toml and setup.py files to make all the scripts runnable from the command line.

In the meantime all the scripts are now functioning and can be acquired by running a git pull command
