2D Arrays In The Lab

[RohanCheri]

Is your feature request related to a problem? Please describe.

• Currently, there are no proper ways to store 2D arrays in the lab. This feature could help implement/create more complex programs in robots such as Micro: Bit and Calliope.

Describe the solution you'd like

• The addition of a 2D array option in the list option menu

Describe alternatives you've considered

• Creating multiple lists and calling each one separately (This ultimately causes for code to become much more verbose though)

Additional context

• The efficiency of the implementation may have to be taken into account in this situation

Good issue for a project proposal (e.g. GSOC, student project)
