Using sqlite as data store

[altunyurt]

This is a suggestion. Using sqlite as data store instead of pickling to binary file might be much easier to handle and provide interoperability with other possible tools.

thanks for your suggestion 👍
pickling to binary is indeed not an ideal way to store the data (it was the quickest to implement). i was looking into adding JSON support at least.
people have pointed out to me something called HAR files, which are used to capture browser activity. sounds like a good candidate for interoperability as well.
