cli: allow sequential quotes in CLI input

[majorsylvie]

team members: Miles, Matteo, Faruk

this is an extension of the quotation-as-one-token issue from before, where we want to allow multiple quotation groups to be made in a single CLI input

I updated the malloc call in parse to calloc in order to avoid manually allocating to 0

This task was never implemented, as it would have changed much of the previous code we had just written in the recently merged quotes PR. However, here is one idea for implementing it:

• Use a stack-like algorithm to track whether quotes are open are closed. Because both the open and closing quotes are the same characters, it will have to be a variation of it, likely which tracks whether an even number of quote characters is present.

For this issue, Faruk and I worked on the documentation. Miles and I looked over the current dev code for some time to figure out how to make the change, but I decided this might be better suited to leave to future classes since it is not a very urgent feature to add, and would have caused many changes over recently added code.

Opening this and placing it in the backlog so future teams can work on it
