Add JSON report as a buffer accessible through the API

[terrybr]

Hi,

It would be very useful if the scan results can be accessed through the API as a buffer.

Thank you!

Hi! sure, I will add it soon!

@terrybr I added a new API function: PESieve_scan_ex - please check it out and let me know if this is what you expected.

For now it is just the scan report, but I will eventually combine the scan report and dump report in one (each in a separate section).

@hasherezade The new API function works as expected! Thank you so much!

@terrybr - the new function (with some improvements) is included in the official release 0.3.5 - please check it out!
