Add quiet routes, plain routes, refactor internal code, add more documentation

[scinscinscin]

This pull request adds a lot of features such as the ability to prepend /quiet and /plain to requests to generate smaller outputs + outputs that don't use ANSI, you can even do both at the same time using /quiet/plain prepend.

Note: /plain is an alias of /cmd and /basic
The new routes have been added to the CLI as well.
I have documented more functions using JSDoc saying what the parameters control and what they return.

Example of a complex query

Generate a quiet version of the history of the deaths in the PH in basic mode

Same query but in CLI
