Install the custom version or latest version of babashka using command line args

Thanks. Two questions:

• Why the change for /tmp/bb instead of /usr/local/bin?
• Does it still support the old way, i.e. only passing a directory name without flags?

Resolved the default path, that tmp path was used while local testing.

Thanks. The only thing left is to fix compatibility with the old way of using the script: install <dir> .

Thanks a lot.
