allow session() to fetch just a section of info

Allow session() to request a subsection of info from bettercap

Description

bettercap.session() takes an optional parameter to request just a part of the tree. The default behavior requests "session", which gets everything. The parameter can be set as "session/wifi" or "session/ble", etc to get just that part of the tree. "session/gps" does not seem to be supported by bettercap, but session/wifi, session/ble and session/hid are.

Motivation and Context

Change required to reduce the data going back and forth in some cases.
