requirements
WIP
- Depending on the package, freeze dependencies as much as possible
- to have 2 versions of requirements
- one with more fixed dependencies
- one with unlocked dependencies
- conda requirements are there for CI mainly
- we should not get unwanted updates at any moment
- have a special day with updates ?
- package requirements are something else
- there should not be too strict constraints in packages, it can prevent other packages like mxcube or daiquiri to work
