Updates

- README.md - added instructions to make sure the setup.sh script was executable as this was not explicitly stated

- setup.sh - updated sed to use `sed -i` to be compatible with Linux, MacOSX and other OS versions and added a check in the local directory taht setup.sh executes in for a pyproject.toml file because the script was looking for the .toml file in the user's home directory and throwing an error
