CLI needs to expose functionality to create a list

[jlewi]

We currently don't expose the functionality to create a new list in the CLI.
This is needed to establish new feeds.

There's code to create a list here

bsctl/pkg/lists/lists.go

Line 48 in 47039a0

func CreateListRecord(client *xrpc.Client, name string, description string) (*comatproto.RepoCreateRecord_Output, error) {

But its not exposed in the CLI.
I think the way to expose it would be to update the apply function to check if the list exists and if not create it

bsctl/pkg/lists/controller.go

Line 35 in 47039a0

if list.DID == "" {
