[Feature] sudo modifier for functions

**Is your feature request related to a problem? Please describe.**
stdlib functions like `std/fs` can require sudo permissions to create/delete/modify files that aren't owned by the user

**Describe the solution you'd like**
the simplest solution is to spawn bash process with function import and it's arguments
```
// sudo function() generates:

sudo bash -c "$(export -f ); ..."
```
cons:
- if function contains other functions, they won't work
- function doesn't have access to arrays
- relatively slow

**Describe alternatives you've considered**
generally require sudo or root user on execution
