Parsing HTTP requests should link to finding

[DePierre]

@DoomTaper has implemented new HTTP parsers (via 713a8fb), where PTP now supports new tool reports that embed the HTTP requests sent to the target.

However, the HTTP requests are being parsed in a bulk-mode. The parser creates a new key transactions in the vulns dictionary returned by ptp.parse() which is not very useful currently since there is no way to find what HTTP request(s) led to the discovery of the finding.

Instead, the parser should for each finding specify the corresponding HTTP requests (as a PoC provided by the tool.

For instance, instead of having an output like:

>>> myptp.parse(pathname='my/other/directory')
[{'ranking': 1}, {'ranking': 2}, {'transactions': [{. . .}, {. . .}, ...]}]

PTP should output:

>>> myptp.parse(pathname='my/other/directory')
[{'ranking': 1, 'transaction': [{. . .}, . . .]}, {'ranking': 2, 'transactions': [{. . .}, . . .]}]
