Review redundant dependencies

[elycheea]

The problem

Adopters are increasingly cautious about bringing in extraneous dependencies as they can often lead to more opportunities for security issues.

Approach

Review list of current dependencies and investigate what work needs to be done that we can remove ahead of v12 or during v12 if they will result in a breaking change.

List of dependencies to review

• lodash
• babel/runtime
• immutability-helper — used in Datagrid (see if we can refactor to remove)

Dependencies specific to Datagrid

These can only be removed after Datagrid is fully removed from our library (v4)

• @dnd-kit/*
• react-table
• react-window

Also ...

• Compare and contrast the bundle size!
