chore(deps): bump compiler to 2022-01-04T16:08:11Z

- disable PR automerge on compiler update (too risky)
- change init file to be a namespace package
- remove version.py (infos can still be retrieved through package meta)
this avoids potential conflicts with other packages we release
- various fixes for compiler compatibility

closes #1272
