README.md export path invalid due to being in the wrong pwd.

[airswing]

Describe the bug
When setting up agave-cli using the README.md, the export paths are invalid after cding into that directory.
When pwd includes agave-cli, appending an additional agave-cli makes the path invalid.
export PATH=$PATH:$PWD/agave-cli/bin

Expected behavior
If the pwd includes agave-cli, then you should only append /bin to it
