Get raw data from backend for post-processing

[MatthewKhouzam]

The front-end of trace compass is able to display data, however, it is formatted by the back-end. It would be good to have access to the raw information, unformatted, for post-processing.

Feature Description:

This feature request can be divided into 4 parts:

• Time Graph (Gantt) charts, using the deepsearch flag can get all we need
• XY Plots need to use a sliding window at the moment to not lose data, having a wrapper
• Event Tables need to have raw columns as opposed to the formatted ones, or a raw tap on each column. (getValue() vs getText()
• Custom tree views like statistics should have an export tsv or something like that. A tree is smallish, and can be sent in one shot. This will also apply to weighted trees and flame graphs.
