Increase base memory limit from 2000 to 4000

[vivienneanthony]

Is your feature request related to a problem? Please describe.
I noticed this warning and wonder if I can change the base memory limit. Could that be increase through the cli?

memory.py:82: UserWarning: Loaded section persona exceeds character limit 2679 - increasing specified memory limit.
  warnings.warn(f"Loaded section {key} exceeds character limit {value['limit']} - increasing specified memory limit.")

Describe the solution you'd like
I would like to be able to set in a config settings file where you can change the base limit.

Describe alternatives you've considered
I noticed in the memory.py both limit: int = 2000 and ("limit", 2000) . Do I have to just change the values? Are there any other files that has a 2000 limit. I think 4000 is a better default.

Is this something that is already implemented?
