Parse JSON values in network requests to improve Excel download

[#1]

Description - Parse JSON values into their own table rows in the network requests view, so that the values within the JSON can be more easily inspected/verified in downloaded Excel files.

Why is this feature important to you - Verifying values within the JSON is very important to verify correct tracking, instead of seeing the long JSON string.

How would you like the feature to work - The debugger automatically parses JSON values into their own (nested) rows in the network requests table.

Current Behaviour - JSON values are one long string value, so in the downloaded Excel file, it is difficult to read the individual values properly without additional manual parsing.
