changes
* move error-related code for groups to its own file

* update group avatar logic

remove unused/duplicate logic

* update `FindGroupsOptions.ToConds()`

allow passing `-1` as the `ParentGroupID`, meaning "find matching groups regardless of the parent group id"

* add `DedupeBy` function to container module

this removes duplicate items from a slice using a custom function

* add `SliceMap` util

works like javascripts's `Array.prototoype.map`, taking in a slice and transforming each element with the provided function

* add group service

functions included so far:
- avatar uploading/deletion
- group deletion
- group creation
- group moving (including moving item inside a group)
- group update
- team management
  - add team
  - remove team
  - update team permissions
  - recalculating team access (in event of group move)
- group searching (only used in frontend/web components for now)
