Upgrade the typer dependency #161

Right now, it is not possible to install pyscript-cli in one environment together with the fastpi-cli because their dependency-constraints prevent resolving the typer dependency.

pyscript-cli depends on typer<=0.9.0, while a recent version of fastapi[standard], which includes the cli, depends on typer>=0.12.3

FastAPI and pyscript are a very obvious pairing, and it would be nice if it was possible to maintain both the frontend and backend in a mono-repo, but right now that's just not possible.

Does anyone remember what the reason was for constraining the maximum version of typer? Maybe I can find time to fix this.
